udf: fix udf_load_pvoldesc()

2015-05-21T13:19:15+00:00

There are some missing braces here which means this function never
succeeds.

udf: improve error management in udf_CS0toUTF8()

2015-05-18T09:23:05+00:00

udf_CS0toUTF8() now returns -EINVAL on error.
udf_load_pvoldesc() and udf_get_filename() do the same.

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.

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.
