* kbuild: Fix comment in Makefile.libMichal Marek2012-01-081-3/+3
| | | | | | | | | | KBUILD_MODNAME is not defined for files that are linked into multiple modules, and trying to change reality to match documentation would result in all sorts of trouble. E.g. options for built-in modules would be called either foo_bar.param, foo.param, or bar.param, depending on the configuration. So just change the comment.

* kbuild: Correctly deal with make options which contain an "s"Jason Wessel2012-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | When using remake, which is based on gnumake, if you invoke an example build as shown below, the build will become silent due to the top level make file incorrectly guessing that the end user wants a silent build because an argument that contained an "s" was used. Here are two examples one with remake and one with straight gnumake. remake --no-extended-errors make --warn-undefined-variables Fix up the top level Makefile to use filter to parse the options that mean silent instead of findstring catching other random arguments containing an "s".

* | arm: remove "optimized" SHA1 routinesLinus Torvalds2011-08-072-212/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1eb19a12bd22 ("lib/sha1: use the git implementation of SHA-1"), the ARM SHA1 routines no longer work. The reason? They depended on the larger 320-byte workspace, and now the sha1 workspace is just 16 words (64 bytes). So the assembly version would overwrite the stack randomly. The optimized asm version is also probably slower than the new improved C version, so there's no reason to keep it around. At least that was the case in git, where what appears to be the same assembly language version was removed two years ago because the optimized C BLK_SHA1 code was faster.

| * | exofs: ios: Move to a per inode components & device-tableBoaz Harrosh2011-08-064-183/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exofs raid engine was saving on memory space by having a single layout-info, single pid, and a single device-table, global to the filesystem. Then passing a credential and object_id info at the io_state level, private for each inode. It would also devise this contraption of rotating the device table view for each inode->ino to spread out the device usage. This is not compatible with the pnfs-objects standard, demanding that each inode can have it's own layout-info, device-table, and each object component it's own pid, oid and creds. So: Bring exofs raid engine to be usable for generic pnfs-objects use by: * Define an exofs_comp structure that holds obj_id and credential info. * Break up exofs_layout struct to an exofs_components structure that holds a possible array of exofs_comp and the array of devices + the size of the arrays. * Add a "comps" parameter to get_io_state() that specifies the ids creds and device array to use for each IO. This enables to keep the layout global, but the device-table view, creds and IDs at the inode level. It only adds two 64bit to each inode, since some of these members already existed in another form. * ios raid engine now access layout-info and comps-info through the passed pointers. Everything is pre-prepared by caller for generic access of these structures and arrays. At the exofs Level: * Super block holds an exofs_components struct that holds the device array, previously in layout. The devices there are in device-table order. The device-array is twice bigger and repeats the device-table twice so now each inode's device array can point to a random device and have a round-robin view of the table, making it compatible to previous exofs versions. * Each inode has an exofs_components struct that is initialized at load time, with it's own view of the device table IDs and creds. When doing IO this gets passed to the io_state together with the layout. While preforming this change. Bugs where found where credentials with the wrong IDs where used to access the different SB objects (super.c). As well as some dead code. It was never noticed because the target we use does not check the credentials. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

| * | exofs: Add offset/length to exofs_get_io_stateBoaz Harrosh2011-08-063-16/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In future raid code we will need to know the IO offset/length and if it's a read or write to determine some of the array sizes we'll need. So add a new exofs_get_rw_state() API for use when writeing/reading. All other simple cases are left using the old way. The major change to this is that now we need to call exofs_get_io_state later at inode.c::read_exec and inode.c::write_exec when we actually know these things. So this patch is kept separate so I can test things apart from other changes. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

There are two bad cases in the old code: 1. Space that should be freed was not. 2. If a file That was big is truncated small, then made bigger again, the holes would not contain zeros but could expose old data.

(I know that was really stupid). Then much later when "register bdi" was added (By Jens) it was registering the pointer to sbi->bdi before the realloc. We never saw this problem because up till now the realloc did not do anything since the device table was small enough to fit in the original allocation. But once we starting testing with large device tables (Bigger then 28) we noticed the crash of writeback operating on a deallocated pointer. * Avoid the all mess by allocating the device-table as a second array and get rid of the variable-sized structure and the rest of this mess. * Take the chance to clean near by structures and comments. * Add a needed dprint on startup to indicate the loaded layout. * Also move the bdi registration to the very end because it will only fail in a low memory, which will probably fail before hand. There are many more likely causes to not load before that. This way the error handling is made simpler. (Just doing this would be enough to fix the BUG) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

* | | vfs: optimize inode cache access patternsLinus Torvalds2011-08-064-34/+106

The path lookup in particular is already quite D$ intensive, and profiles show that accessing the 'inode->i_op->xyz' fields is quite costly. We already optimized the dcache to not unnecessarily load the d_op structure for members that are often NULL using the DCACHE_OP_xyz bits in dentry->d_flags, and this does something very similar for the inode ops that are used during pathname lookup. It also re-orders the fields so that the fields accessed by 'stat' are together at the beginning of the inode structure, and roughly in the order accessed. The effect of this seems to be in the 1-2% range for an empty kernel "make -j" run (which is fairly kernel-intensive, mostly in filename lookup), so it's visible. The numbers are fairly noisy, though, and likely depend a lot on exact microarchitecture. So there's more tuning to be done. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number.

This enables interrupts during a time where interrupts were expected to be disabled, and can have strange side effects on drivers that expected interrupts to be disabled. This is not a bug since the documentation clearly states that only _put_sync_suspend() is safe in IRQ-safe mode. However, pm_runtime_put_sync() could be made safe when in IRQ-safe mode by releasing the spinlock but not re-enabling interrupts, which is what this patch aims to do. Problem was found when using some buggy drivers that set pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled context.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The local variable ret is defined twice in pm_genpd_poweron(), which causes this function to always return 0, even if the PM domain's .power_on() callback fails, in which case an error code should be returned. Remove the wrong second definition of ret and additionally remove an unnecessary definition of wait from pm_genpd_poweron(). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
