* [PATCH] Poll cleanups/microoptimizationsVadim Lobanov2006-06-231-32/+51
| | | | | | | | | | | | | | | The "count" and "pt" variables are declared and modified by do_poll(), as well as accessed and written indirectly in the do_pollfd() subroutine. This patch pulls all handling of these variables into the do_poll() function, thereby eliminating the odd use of indirection in do_pollfd(). This is done by pulling the "struct pollfd" traversal loop from do_pollfd() into its only caller do_poll(). As an added bonus, the patch saves a few clock cycles, and also adds comments to make the code easier to follow.

* [PATCH] vfs: add lock owner argument to flush operationMiklos Szeredi2006-06-2314-16/+16
| | | | | | | | | | | | | | | | | | | Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.

* [PATCH] locks: clean up locks_remove_posix()Miklos Szeredi2006-06-231-20/+5
| | | | | | | | | | | | | locks_remove_posix() can use posix_lock_file() instead of doing the lock removal by hand. posix_lock_file() now does exacly the same. The comment about pids no longer applies, posix_lock_file() takes only the owner into account.

* [PATCH] locks: don't do unnecessary allocationsMiklos Szeredi2006-06-231-3/+10
| | | | | | | | | | | | | | | | posix_lock_file() always allocates new locks in advance, even if it's easy to determine that no allocations will be needed.

* [PATCH] locks: don't unnecessarily fail posix lock operationsMiklos Szeredi2006-06-231-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | posix_lock_file() was too cautious, failing operations on OOM, even if they didn't actually require an allocation. This has the disadvantage, that a failing unlock on process exit could lead to a memory leak. There are two possibilites for this: - filesystem implements .lock() and calls back to posix_lock_file(). On cleanup of files_struct locks_remove_posix() is called which should remove all locks belonging to files_struct. However if filesystem calls posix_lock_file() which fails, then those locks will never be freed. - if a file is closed while a lock is blocked, then after acquiring fcntl_setlk() will undo the lock. But this unlock itself might fail on OOM, again possibly leaking the lock. The solution is to move the checking of the allocations until after it is sure that they will be needed. This will solve the above problem since unlock will always succeed unless it splits an existing region.

* [PATCH] s390_hypfs filesystemMichael Holzheu2006-06-237-1/+1250
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On zSeries machines there exists an interface which allows the operating system to retrieve LPAR hypervisor accounting data. For example, it is possible to get usage data for physical and virtual cpus. In order to provide this information to user space programs, I implemented a new virtual Linux file system named 's390_hypfs' using the Linux 2.6 libfs framework. The name 's390_hypfs' stands for 'S390 Hypervisor Filesystem'. All the accounting information is put into different virtual files which can be accessed from user space. All data is represented as ASCII strings. When the file system is mounted the accounting information is retrieved and a file system tree is created with the attribute files containing the cpu information. The content of the files remains unchanged until a new update is made. An update can be triggered from user space through writing 'something' into a special purpose update file. We create the following directory structure: <mount-point>/ update cpus/ <cpu-id> type mgmtime <cpu-id> ... hyp/ type systems/ <lpar-name> cpus/ <cpu-id> type mgmtime cputime onlinetime <cpu-id> ... <lpar-name> cpus/ ... - update: File to trigger update - cpus/: Directory for all physical cpus - cpus/<cpu-id>/: Directory for one physical cpu. - cpus/<cpu-id>/type: Type name of physical zSeries cpu. - cpus/<cpu-id>/mgmtime: Physical-LPAR-management time in microseconds. - hyp/: Directory for hypervisor information - hyp/type: Typ of hypervisor (currently only 'LPAR Hypervisor') - systems/: Directory for all LPARs - systems/<lpar-name>/: Directory for one LPAR. - systems/<lpar-name>/cpus/<cpu-id>/: Directory for the virtual cpus - systems/<lpar-name>/cpus/<cpu-id>/type: Typ of cpu. - systems/<lpar-name>/cpus/<cpu-id>/mgmtime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the hypervisor and was not provided to the LPAR (LPAR overhead). - systems/<lpar-name>/cpus/<cpu-id>/cputime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the LPAR. - systems/<lpar-name>/cpus/<cpu-id>/onlinetime: Accumulated number of microseconds during which the logical CPU has been online. As mount point for the filesystem /sys/hypervisor/s390 is created. The update process is triggered when writing 'something' into the 'update' file at the top level hypfs directory. You can do this e.g. with 'echo 1 > update'. During the update the whole directory structure is deleted and built up again.

* [PATCH] swsusp: use less memory during resumeRafael J. Wysocki2006-06-232-58/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make swsusp allocate only as much memory as needed to store the image data and metadata during resume. Without this patch swsusp additionally allocates many page frames that will conflict with the "original" locations of the image data and are considered as "unsafe", treating them as "eaten" pages (ie. allocated but unusable). The patch makes swsusp allocate as many pages as it'll need to store the data read from the image in one shot, creating a list of allocated "safe" pages, and use the observation that all pages allocated by it are marked with the PG_nosave and PG_nosave_free flags set.  Namely, when it's about to load an image page, swsusp can check whether the page frame corresponding to the "original" location of this page has been allocated (ie. if the page frame has the PG_nosave and PG_nosave_free flags set) and if so, it can load the page directly into this page frame.  Otherwise it uses an allocated "safe" page from the list to store the data that will be copied to their "original" location later on. This allows us to save many page copyings and page allocations during resume and in the future it may allow us to load images greater than 50% of the normal zone. Signed-off-by: Rafael J.

* [PATCH] i386: extra checks in show_registers()Chuck Ebbert2006-06-231-2/+3
| | | | | | | | | | | Sometimes thread_info and task_struct get out-of-sync with each other. Printing task.thread_info in show_registers() can help spot this. And when task_struct is corrupt then task.comm can contain garbage, so only print as many characters as it can hold.

* [PATCH] i386: fix get_segment_eip() with vm86 segmentsChuck Ebbert2006-06-231-4/+7
| | | | | | | | | | | | | | | | We need to check for vm86 mode first before looking at selector privilege bits. Segment limit is always base + 64k and only the low 16 bits of EIP are significant in vm86 mode.
