ext2/3: use prandom_u32() instead of get_random_bytes()

2014-03-04T11:19:03Z

Many of the uses of get_random_bytes() do not actually need cryptographically secure random numbers. Replace those uses with a call to prandom_u32(), which is faster and which doesn't consume entropy from the /dev/random driver. The commit dd1f723bf56bd96efc9d90e9e60dc511c79de48f has made that for ext4, and i did the same for ext2/3. Signed-off-by: Zhang Zhen Signed-off-by: Jan Kara

ext3: Fix error handling on inode bitmap corruption

2012-01-09T12:52:07Z

When insert_inode_locked() fails in ext3_new_inode() it most likely means inode bitmap got corrupted and we allocated again inode which is already in use. Also doing unlock_new_inode() during error recovery is wrong since inode does not have I_NEW set. Fix the problem by jumping to fail: (instead of fail_drop:) which declares filesystem error and does not call unlock_new_inode(). Reviewed-by: Eric Sandeen Signed-off-by: Jan Kara

ext3: remove deprecated oldalloc

2011-08-17T09:42:19Z

For a long time now orlov is the default block allocator in the ext3. It performs better than the old one and no one seems to claim otherwise so we can safely drop it and make oldalloc and orlov mount option deprecated. Signed-off-by: Lukas Czerner Signed-off-by: Jan Kara

ext3: Add fixed tracepoints

2011-06-25T15:29:51Z

This commit adds fixed tracepoints to the ext3 code. It is based on ext4 tracepoints, however due to the differences of both file systems, there are some tracepoints missing (those for delaloc and for multi-block allocator) and there are some ext3 specific as well (for reservation windows). Here is a list: ext3_free_inode ext3_request_inode ext3_allocate_inode ext3_evict_inode ext3_drop_inode ext3_mark_inode_dirty ext3_write_begin ext3_ordered_write_end ext3_writeback_write_end ext3_journalled_write_end ext3_ordered_writepage ext3_writeback_writepage ext3_journalled_writepage ext3_readpage ext3_releasepage ext3_invalidatepage ext3_discard_blocks ext3_request_blocks ext3_allocate_blocks ext3_free_blocks ext3_sync_file_enter ext3_sync_file_exit ext3_sync_fs ext3_rsv_window_add ext3_discard_reservation ext3_alloc_new_reservation ext3_reserved ext3_forget ext3_read_block_bitmap ext3_direct_IO_enter ext3_direct_IO_exit ext3_unlink_enter ext3_unlink_exit ext3_truncate_enter ext3_truncate_exit ext3_get_blocks_enter ext3_get_blocks_exit ext3_load_inode Signed-off-by: Lukas Czerner Cc: Jan Kara Signed-off-by: Jan Kara
