After series of review for the the feature The complete functionality is broken down into smaller subsets. v3: - fix i_disksize and mmu_private comments(uninit/initialized) - remove unneeded condition in fat_bmap. - use mmu_private instead of fclus in fat_fallocate. - make function mark buffer new for block in fallocated region. - use flags for bmap. - use mmu_private instead of i_size in direct_IO. - use flags and remove i_mutex in bmap. - update vfat documentation. v2: - remove a stary unlock(from Dan Carpenter) - check ->mmu_private and ->i_disksize to truncate uninitialized data. Namjae Jeon (6): fat: add i_disksize to represent uninitialized size fat: add fat_fallocate operation fat: zero out seek range on _fat_get_block fat: fallback to buffered write in case of fallocatded region on direct IO fat: permit to return phy block number by fibmap in fallocated region fat: update the limitation for fat fallocate -- 1.7.9.5
