fs: Remove ext3 filesystem driver

2015-07-23T18:59:40+00:00

The functionality of ext3 is fully supported by ext4 driver. Major distributions (SUSE, RedHat) already use ext4 driver to handle ext3 filesystems for quite some time. There is some ugliness in mm resulting from jbd cleaning buffers in a dirty page without cleaning page dirty bit and also support for buffer bouncing in the block layer when stable pages are required is there only because of jbd. So let's remove the ext3 driver. This saves us some 28k lines of duplicated code. Acked-by: Theodore Ts'o Signed-off-by: Jan Kara

ext3: remove an unneeded check in ext3_new_blocks()

We know "fatal" is zero here. The code can be simplified a bit by assigning directly. Signed-off-by: Dan Carpenter Signed-off-by: Jan Kara

ext3: Avoid underflow of in ext3_trim_fs()

2012-11-19T20:36:12+00:00

Currently if len argument in ext3_trim_fs() is smaller than one block, the 'end' variable underflow. Avoid that by returning EINVAL if len is smaller than file system block. Also remove useless unlikely(). Signed-off-by: Lukas Czerner Signed-off-by: Jan Kara

ext3: use memweight()

2012-07-31T00:25:16+00:00

Convert ext3_count_free() to use memweight() instead of table lookup based counting clear bits implementation. This change only affects the code segments enabled by EXT3FS_DEBUG. Note that this memweight() call can't be replaced with a single bitmap_weight() call, although the pointer to the memory area is aligned to long-word boundary. Because the size of the memory area may not be a multiple of BITS_PER_LONG, then it returns wrong value on big-endian architecture. This also includes the following changes. - Remove unnecessary map == NULL check in ext3_count_free() which always takes non-null pointer as the memory area. - Fix printk format warning that only reveals with EXT3FS_DEBUG.

ext3: fix start and len arguments handling in ext3_trim_fs()

2012-03-02T16:47:40+00:00

The overflow might happen when passing blocknr into ext3_get_group_no_and_offset(), because it expects type ext3_fsblk_t which might be smaller than uint64_t. This will most likely happen when calling FITRIM with the default argument len = ULLONG_MAX. Fix this by using "end" variable instead of "start+len" as it is easier to get right and specifically check that the end is not beyond the end of the file system, so we are sure that the result of get_group_no_and_offset() will not overflow. Otherwise truncate it to the size of the file system. Signed-off-by: Lukas Czerner Cc: Jan Kara Signed-off-by: Jan Kara

ext3: Don't call dquot_free_block() if we don't update anything

2012-02-29T20:53:46+00:00

dquot_free_block() is called in the end of ext3_new_blocks() and updates information of the inode structure. However, this update is not necessary if the number of blocks we requested is equal to the number of allocated blocks. Signed-off-by: Kazuya Mio Signed-off-by: Jan Kara
