* [PATCH] PROC_NUMBUF is wrongAndrew Morton2006-10-17
| | | | | | | | | | Actually, the decimal representation of a 32-bit signed number can take 12 bytes, including the \0. And then some code adds a \n as well, so let's give it 13 bytes. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] null dereference in fs/jbd2/journal.cDave Kleikamp2006-10-17
| | | | | | | | | | | | | | | | This is Eric Sesterhenn's jbd patch applied to jbd2. Commit: 41716c7c21b15e7ecf14f0caf1eef3980707fb74 His words: Since commit d1807793e1e7e502e3dc047115e9dbc3b50e4534 we dereference a NULL pointer. Coverity id #1432. We set journal to NULL, and use it directly afterwards.

* [PATCH] Fix core files so they make sense to gdb...Petr Vandrovec2006-10-15
| | | | | | | | | | | | It is silly to use non-static variable for writting zeroes to the file. And more seriously, foffset in core dump file dump function was incremented too much, so some parts of core dump were shifted by size of few phdrs and notes down, so although gdb was able to load that file, it did not make lot of sense - in my test case data pages were shifted down by about 900 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a size calculation error. The size was incorrect being computed as a negative length and then being passed to an unsigned parameter.

* | [PATCH] Get core dump code to work...Petr Vandrovec2006-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file based core dump code was broken by pipe changes - a relative llseek returns the absolute file position on success, not the relative one, so dump_seek() always failed when invoked with non-zero current position. Only success/failure can be tested with relative lseek, we have to trust kernel that on success we've got right file offset. With this fix in place I have finally real core files instead of 1KB fragments...

* | | [PATCH] block layer: ioprio_best function fixVasily Tarasov2006-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ioprio_best function first checks wethere aioprio or bioprio equals IOPRIO_CLASS_NONE (ioprio_valid() macros does that) and if it is so it returns bioprio/aioprio appropriately. Thus the next four lines, that set aclass/bclass to IOPRIO_CLASS_BE, if aclass/bclass == IOPRIO_CLASS_NONE, are never executed. The second problem: if aioprio from class IOPRIO_CLASS_NONE and bioprio from class IOPRIO_CLASS_IDLE are passed to ioprio_best function, it will return IOPRIO_CLASS_IDLE. It means that during __make_request we can merge two requests and set the priority of merged request to IDLE, while one of the initial requests originates from a process with NONE (default) priority. So we can get a situation when a process with default ioprio will experience IO starvation, while there is no process from real-time class in the system. Just removing ioprio_valid check should correct situation. Signed-off-by: Vasily Tarasov <vtaras@openvz.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* | [PATCH] VFS: Destroy the dentries contributed by a superblock on unmountingDavid Howells2006-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch destroys all the dentries attached to a superblock in one go by: (1) Destroying the tree rooted at s_root. (2) Destroying every entry in the anon list, one at a time. (3) Each entry in the anon list has its subtree consumed from the leaves inwards. This reduces the amount of work generic_shutdown_super() does, and avoids iterating through the dentry_unused list. Note that locking is almost entirely absent in the shrink_dcache_for_umount*() functions added by this patch. This is because: (1) at the point the filesystem calls generic_shutdown_super(), it is not permitted to further touch the superblock's set of dentries, and nor may it remove aliases from inodes; (2) the dcache memory shrinker now skips dentries that are being unmounted; and (3) the superblock no longer has any external references through which the VFS can reach it. Given these points, the only locking we need to do is when we remove dentries from the unused list and the name hashes, which we do a directory's worth at a time. We also don't need to guard against reference counts going to zero unexpectedly and removing bits of the tree we're working on as nothing else can call dput(). A cut down version of dentry_iput() has been folded into shrink_dcache_for_umount_subtree() function. Apart from not needing to unlock things, it also doesn't need to check for inotify watches. In this version of the patch, the complaint about a dentry still being in use has been expanded from a single BUG_ON() and now gives much more information.
