mb_groups details of multiblock allocator buddy cache of free blocks
mb_history multiblock allocation history
- stats controls whether the multiblock allocator should start
- collecting statistics, which are shown during the unmount
- group_prealloc the multiblock allocator will round up allocation
- requests to a multiple of this tuning parameter if the
- stripe size is not set in the ext4 superblock
- max_to_scan The maximum number of extents the multiblock allocator
- will search to find the best extent
- min_to_scan The minimum number of extents the multiblock allocator
- will search to find the best extent
- order2_req Tuning parameter which controls the minimum size for
- requests (as a power of 2) where the buddy cache is
- used
- stream_req Files which have fewer blocks than this tunable
- parameter will have their blocks allocated out of a
- block group specific preallocation pool, so that small
- files are packed closely together. Each large file
- will have its blocks allocated out of its own unique
- preallocation pool.
-inode_readahead Tuning parameter which controls the maximum number of
- inode table blocks that ext4's inode table readahead
- algorithm will pre-read into the buffer cache
