It used to be called directly, but that got lost in 2.1.87-pre1. Similar breakage in ataflop got fixed 3 years ago, this one had gone unnoticed. Signed-off-by:

pcbit: kill 'may be used uninitialized' warning. although the code does eventually fill the 32 bits it cares about, the variable truly is accessed uninitialized in each macro. Easier to just clean it up now. sc: fix a ton of obviously incorrect printk's (some with missing arguments even) Signed-off-by:

- Calculate a variable in bvec_alloc_bs() only once needed, not earlier (bio.o down from 18408 to 18376 Bytes, 32 Bytes saved, probably due to data locality improvements). - Init variable idx to silence a gcc warning which already existed in the unmodified original base file (bvec_alloc_bs() handles idx correctly, so there's no need for the warning): fs/bio.c: In function `bio_alloc_bioset': fs/bio.c:169: warning: `idx' may be used uninitialized in this function Signed-off-by:

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.

Make sure all dentries refs are released before calling kill_anon_super() so that the assumption that generic_shutdown_super() can completely destroy the dentry tree for there will be no external references holds true. What was being done in the put_super() superblock op, is now done in the kill_sb() filesystem op instead, prior to calling kill_anon_super(). This makes the struct autofs_sb_info::root member variable redundant (since sb->s_root is still available), and so that is removed. The calls to shrink_dcache_sb() are also removed since they're also redundant as shrink_dcache_for_umount() will now be called after the cleanup routine. Signed-off-by:

What was being done in the put_super() superblock op, is now done in the kill_sb() filesystem op instead, prior to calling kill_block_super(). Changes made in [try #2]: (*) reiserfs_kill_sb() now checks that the superblock FS info pointer is set before trying to dereference it. Signed-off-by: -

- In parameter descriptions, strip all whitespace between the parameter name (e.g., @len) and its description so that the description is indented uniformly in text and man page modes. Previously, spaces or tabs (which are used for cleaner source code viewing) affected the produced output in a negative way. Before (man mode): to Destination address, in user space. from Source address, in kernel space. n Number of bytes to copy. After (man mode): to Destination address, in user space. from Source address, in kernel space. n Number of bytes to copy. - Fix/clarify a few function description comments.

Bug reported and fixed by Tilman Schmidt <tilman@imap.cc>: if lockdep is enabled then log messages make it to /var/log/messages belatedly. The reason is a missed wakeup of klogd. Initially there was only a lockdep_internal() protection against lockdep recursion within vprintk() - it grew the 'outer' lockdep_off()/on() protection only later on. But that lockdep_off() made the release_console_sem() within vprintk() always happen under the lockdep_internal() condition, causing the bug. The right solution to remove the inner protection against recursion here - the outer one is enough. Signed-off-by:

I was looking at lockdep-desing.txt and i guess i am confused with the changes with respect to fd7bcea3. It says + '.' acquired while irqs enabled + '+' acquired in irq context + '-' acquired in process context with irqs disabled + '?' read-acquired both with irqs enabled and in irq context + But the get_usage_chars() function does this for '-' if (class->usage_mask & LOCKF_ENABLED_HARDIRQS) *c1 = '-'; So i guess what would be correct would be '.' acquired while irqs disabled '+' acquired in irq context '-' acquired with irqs enabled '?' read acquired in irq context with irqs enabled.
