      "message": "ext4: mballoc fix mb_normalize_request algorithm for 1KB block size filesystems\n\nIn case of inode preallocation, the number of blocks to allocate depends\non the file size and it is calculated in ext4_mb_normalize_request().\nEach group in the filesystem is then checked to find one that can be\nused for allocation; this is done in ext4_mb_good_group().\n\nWhen a file bigger than 4MB is created, the requested number of blocks\nto preallocate, calculated by ext4_mb_normalize_request is 4096.\nHowever for a filesystem with 1KB block size, the maximum size of the\nblock buddies used by the multiblock allocator is 2048, so none of\ngroups in the filesystem satisfies the search criteria in\next4_mb_good_group(). Scanning all the filesystem groups impacts\nperformance.\n\nThis was demonstrated by using a freshly created, 70GB, 1k block\nfilesystem, with caches dropped write before the test via\n/proc/sys/vm/drop_caches, and with the filesystem mounted with\nnodelalloc and nodealloc,nomballoc.  The time to write an 8 megabyte\nfile using \"dd if\u003d/dev/zero of\u003d/mnt/test/fo bs\u003d8k count\u003d1k conv\u003dfsync\"\ntook 35.5091 seconds (236kB/s) with nodellaloc, and 0.233754 seconds\n(35.9 MB/s) with the nodelloc,nomballoc options.  With a 1TB partition,\nit took several minutes to write 8MB!\n\nThis patch modifies the algorithm in ext4_mb_normalize_group_request to\ncalculate the number of blocks to allocate by taking into account the\nmaximum size of free blocks chunks handled by the multiblock allocator.\n\nIt has also been tested for filesystems with 2KB and 4KB block sizes to\nensure that those cases don\u0027t regress.\n\nReviewed-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: Valerie Clement \u003cvalerie.clement@bull.net\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n"
