udf: destroy sbi mutex in put_super

2015-01-12T09:56:04+00:00

Call mutex_destroy() on superblock mutex in udf_put_super()
otherwise mutex debugging code isn't able to detect that
mutex is used after being freed.
(thanks to Jan Kara for complete definition).

udf: One function call less in udf_fill_super() after error detection

2014-11-19T20:56:06+00:00

The iput() function was called in up to three cases by the udf_fill_super()
function during error handling even if the passed data structure element
contained still a null pointer. This implementation detail could be improved
by the introduction of another jump label.

udf: Deletion of unnecessary checks before the function call "iput"

2014-11-19T20:55:45+00:00

The iput() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

udf: Fix loading of special inodes

2014-10-09T11:06:14+00:00

Some UDF media have special inodes (like VAT or metadata partition
inodes) whose link_count is 0. Thus commit 4071b9136223 (udf: Properly
detect stale inodes) broke loading these inodes because udf_iget()
started returning -ESTALE for them. Since we still need to properly
detect stale inodes queried by NFS, create two variants of udf_iget() -
one which is used for looking up special inodes (which ignores
link_count == 0) and one which is used for other cases which return
ESTALE when link_count == 0.

udf: Make udf_read_inode() and udf_iget() return error

2014-09-04T19:36:35+00:00

Currently __udf_read_inode() wasn't returning anything and we found out
whether we succeeded reading inode by checking whether inode is bad or
not. udf_iget() returned NULL on failure and inode pointer otherwise.
Make these two functions properly propagate errors up the call stack and
use the return value in callers.

fs: push sync_filesystem() down to the file system's remount_fs()

2014-03-13T14:14:33+00:00

Previously, the no-op "mount -o mount /dev/xxx" operation when the
file system is already mounted read-write causes an implied,
unconditional syncfs().  This seems pretty stupid, and it's certainly
documented or guaraunteed to do this, nor is it particularly useful,
except in the case where the file system was mounted rw and is getting
remounted read-only.

However, it's possible that there might be some file systems that are
actually depending on this behavior.  In most file systems, it's
probably fine to only call sync_filesystem() when transitioning from
read-write to read-only, and there are some file systems where this is
not needed at all (for example, for a pseudo-filesystem or something
like romfs).
