[PATCH v7 0/7] fat (exportfs): support stale_rw and nostale_ro mount option.
From: Namjae Jeon This patch set eliminates the client side ESTALE errors when a FAT partition exported over NFS has it's dentries evicted from the cache. The idea is to find the on-disk location_'i_pos' of the dirent of the inode that has been evicted and use it to rebuild the inode. Change log v7: Assign i_pos = MSDOS_ROOT_INO in fat_read_root() and drop check in fat _getattr(). Remove __packed attribute from struct fat_fid. Make code in fat_encode_fh() more readable. v6: Dummy inode approach to eliminate custom function fat_traverse_cluster(). v5: Modified fat_ent_read() arguments so that the custom function fat_read_next_clus() can be eliminated. v(no name): Define two nfs export_operation structures, one for 'stale_rw' mounts and the other for 'nostale_ro' fat_nfs_get_inode does not hold i_mutex of parent directory. So introduce fat_lock_build_inode(). v4: Instead of assigning i_pos to inode->i_ino, assign it to kstat->ino v3: Dropped busy-list approach and made the filesystem read only when rebuilding evicted inodes, by providing stale_rw and nostale_ro mount options v2: Introduced a list of busy i_pos values for inodes that are unlinked but having open file handles. Did this to avoid assigning such i_pos values to new files created at same location. v1: Permanent inode number based approach by assigning i_pos to i_ino. Added custom function fat_read_next_clus() and fat_traverse_cluster() to read disk entries. Namjae Jeon (7): fat: Introduce 2 new values for the -o nfs mount option fat: move fat_i_pos_read to fat.h fat: introduce a helper fat_get_blknr_offset() fat: restructure export_operations fat (exportfs): rebuild inode if ilookup() fails fat (exportfs): rebuild directory-inode if fat_dget() fails Documentation: update nfs option in filesystem/vfat.txt --- 1.7.9.5 -- 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/
