| | | | | | | | | | | | | | | | | | | | Some callers to block-layer commit_write function treat non-zero return as error, notably the loopback mount driver sometimes used in conjunction with JFFS2 on NAND flash for bad block avoidance, etc. Return zero for success as do various other commit_write functions.

| * [JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi2005-11-0617-197/+1359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.

| | | | | | | | | | | | | | | | | | | | JFFS2 uses f->dents to store the pointer to the symlink target string (in case the inode is symlink).

* [PATCH] fix missing includesTim Schmielau2005-10-302-0/+3
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] jffs2: fix symlink error handlingAl Viro2005-08-191-4/+6
| | | | | | | | | | | | | | | | | The current calling conventions for ->follow_link() are already fairly complex. What we have is 1) you can return -error; then you must release nameidata yourself and ->put_link() will _not_ be called. 2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0 3) you can do nd_set_link(nd, path) and return 0 4) you can return 0 (after having moved nameidata yourself) jffs2 follow_link() is broken - it has an exit where it returns -EIO and leaks nameidata.
