Theodore Ts'o 2ed5724d5a ext4: add cond_resched() to ext4_free_blocks() & ext4_mb_regular_allocator() ... For a file systems with a very large number of block groups, if all of the block group bitmaps are in memory and the file system is relatively badly fragmented, it's possible ext4_mb_regular_allocator() to take a long time trying to find a good match. This is especially true if the tuning parameter mb_max_to_scan has been sent to a very large number. So add a cond_resched() to avoid soft lockup warnings and to provide better system responsiveness. For ext4_free_blocks(), if we are deleting a large range of blocks, and data=journal is enabled so that EXT4_FREE_BLOCKS_FORGET is passed, the loop to call sb_find_get_block() and to call ext4_forget() can take over 10-15 milliseocnds or more. So it's better to add a cond_resched() here a well. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>		2013-06-12 11:43:02 -04:00
