udf: Fix handling of i_blocks

2012-02-29T20:53:47+00:00

Commit 36350462 removed unused quota support from UDF. As an unfortunate
sideeffect it also removed updates of i_blocks so all files had i_block == 0.
Fix the problem by returning updates of file space back to UDF allocation and
freeing functions.

udf: Neaten udf_debug uses

2011-10-31T22:43:58+00:00

Just whitespace and argument alignment.
Introduce some checkpatch warnings that deserve to be ignored.

udf: use little-endian bitops

2011-03-24T02:46:19+00:00

As a preparation for removing ext2 non-atomic bit operations from
asm/bitops.h.  This converts ext2 non-atomic bit operations to
little-endian bit operations.

UDF: Fix compiler warning

Fix compiler warning

fs/udf/balloc.c: In function 'udf_bitmap_new_block':
fs/udf/balloc.c:273: warning: passing argument 1 of '_find_next_bit_le' from incompatible pointer type
fs/udf/balloc.c:285: warning: passing argument 1 of '_find_next_bit_le' from incompatible pointer type
fs/udf/balloc.c:311: warning: passing argument 1 of '_find_next_bit_le' from incompatible pointer type
fs/udf/balloc.c:325: warning: passing argument 1 of '_find_next_bit_le' from incompatible pointer type

The main fix is to add a cast in ext2_find_next_bit().

As all other usage locations of udf_find_next_one_bit()
directly use bh->b_data (which is a char *), the useless
(char *) cast in line 311 can be removed, too.

udf: Call udf_add_free_space() for more blocks at once in udf_free_blocks()

2011-01-06T16:03:56+00:00

There's no need to call udf_add_free_space() for one block at a time. It saves
us noticeable amount of work and yields different result from the original
code only if the filesystem is corrupted and bitmap bit is already cleared.
In such case counter of free blocks is probably wrong anyways so the change
does not matter.

udf: Remove dead quota code

2010-05-24T12:10:19+00:00

Quota on UDF is non-functional at least since 2.6.16 (I'm too lazy to
do more archeology) because it does not provide .quota_write and .quota_read
functions and thus quotaon(8) just returns EINVAL. Since nobody complained
for all those years and quota support is not even in UDF standard just nuke
it.

udf: potential integer overflow

2010-04-08T13:35:20+00:00

bloc->logicalBlockNum is unsigned so it's never less than zero.

When I saw that, it made me worry that "bloc->logicalBlockNum + count"
could overflow.  That's why I changed the check for less than zero
to an overflow check.  (The test works because "count" is also
unsigned.)

udf: use ext2_find_next_bit

2010-03-09T16:15:18+00:00

Use ext2_find_next_bit (generic_find_next_le_bit) to find the set bit
in little endian bitmap region.

dquot: cleanup space allocation / freeing routines

2010-03-04T23:20:28+00:00

Get rid of the alloc_space, free_space, reserve_space, claim_space and
release_rsv dquot operations - they are always called from the filesystem
and if a filesystem really needs their own (which none currently does)
it can just call into it's own routine directly.

Move shared logic into the common __dquot_alloc_space,
dquot_claim_space_nodirty and __dquot_free_space low-level methods,
and rationalize the wrappers around it to move as much as possible
code into the common block for CONFIG_QUOTA vs not.  Also rename
all these helpers to be named dquot_* instead of vfs_dq_*.
