[PATCH v4 0/6] fat: additions to support fat_fallocate
From: Namjae Jeon This patch set provides support for doing fallocate operation on FAT filesystem. After series of review for the the feature The complete functionality is broken down into smaller subsets. v4: - ->i_disksize is aligned by block size in fill_inode. - use i_disksize when computing the number of cluster for fallocate. - make fat_get_block_bmap to avoid race issue. - use __fat_write_inode() with inode_needs_sync() in evict. 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 -- 1.7.11-rc0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
