Date: Sun, 8 Aug 2010 11:52:17 -0400 From: Valerie Aurora <vaurora@...hat.com> To: Alexander Viro <viro@...iv.linux.org.uk> Cc: Miklos Szeredi <miklos@...redi.hu>, Jan Blunck <jblunck@...e.de>, Christoph Hellwig <hch@...radead.org>, linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, Valerie Aurora <vaurora@...hat.com> Subject: [PATCH 00/39] Union mounts - return d_ino from lower fs After questioning the value of d_ino, I am now convinced of its utility. This version of union mounts fills in d_ino of fallthru directory entries with the inode number of the target. You still need to stat() the entry to get st_dev if you want to do a file uniqueness comparison using the inode. See the patch introducing generic_readdir_fallthru() for the implementation. -VAL Felix Fietkau (2): whiteout: jffs2 whiteout support fallthru: jffs2 fallthru support Jan Blunck (10): VFS: Make lookup_hash() return a struct path autofs4: Save autofs trigger's vfsmount in super block info whiteout/NFSD: Don't return information about whiteouts to userspace whiteout: Add vfs_whiteout() and whiteout inode operation whiteout: Set opaque flag if new directory was previously a whiteout whiteout: Allow removal of a directory with whiteouts whiteout: Split of ext2_append_link() from ext2_add_link() whiteout: ext2 whiteout support union-mount: Introduce MNT_UNION and MS_UNION flags union-mount: Call do_whiteout() on unlink and rmdir in unions Valerie Aurora (27): VFS: Comment follow_mount() and friends VFS: Add read-only users count to superblock whiteout: tmpfs whiteout support fallthru: Basic fallthru definitions union-mount: Union mounts documentation union-mount: Introduce union_dir structure and basic operations union-mount: Free union dirs on removal from dcache union-mount: Support for union mounting file systems union-mount: Implement union lookup union-mount: Copy up directory entries on first readdir() union-mount: Add generic_readdir_fallthru() helper fallthru: ext2 fallthru support fallthru: tmpfs fallthru support VFS: Split inode_permission() and create path_permission() VFS: Create user_path_nd() to lookup both parent and target union-mount: In-kernel file copyup routines union-mount: Implement union-aware access()/faccessat() union-mount: Implement union-aware link() union-mount: Implement union-aware rename() union-mount: Implement union-aware writable open() union-mount: Implement union-aware chown() union-mount: Implement union-aware truncate() union-mount: Implement union-aware chmod()/fchmodat() union-mount: Implement union-aware lchown() union-mount: Implement union-aware utimensat() union-mount: Implement union-aware setxattr() union-mount: Implement union-aware lsetxattr() Documentation/filesystems/union-mounts.txt | 752 +++++++++++++++++++++++++++ Documentation/filesystems/vfs.txt | 16 +- fs/Kconfig | 13 + fs/Makefile | 1 + fs/autofs4/autofs_i.h | 1 + fs/autofs4/init.c | 11 +- fs/autofs4/root.c | 6 + fs/compat.c | 9 + fs/dcache.c | 32 ++- fs/ext2/dir.c | 248 +++++++++- fs/ext2/ext2.h | 4 + fs/ext2/inode.c | 11 +- fs/ext2/namei.c | 85 +++- fs/ext2/super.c | 7 + fs/jffs2/dir.c | 117 +++++- fs/jffs2/fs.c | 4 + fs/jffs2/super.c | 2 +- fs/libfs.c | 23 +- fs/namei.c | 754 ++++++++++++++++++++++++---- fs/namespace.c | 289 +++++++++++- fs/nfsd/nfs3xdr.c | 5 + fs/nfsd/nfs4xdr.c | 5 + fs/nfsd/nfsxdr.c | 4 + fs/open.c | 116 ++++- fs/readdir.c | 18 + fs/super.c | 24 + fs/union.c | 752 +++++++++++++++++++++++++++ fs/union.h | 80 +++ fs/utimes.c | 14 +- fs/xattr.c | 65 ++- include/linux/dcache.h | 19 +- include/linux/ext2_fs.h | 8 + include/linux/fs.h | 28 + include/linux/jffs2.h | 8 + include/linux/mount.h | 6 +- include/linux/namei.h | 2 + mm/shmem.c | 193 +++++++- 37 files changed, 3549 insertions(+), 183 deletions(-) create mode 100644 Documentation/filesystems/union-mounts.txt create mode 100644 fs/union.c create mode 100644 fs/union.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
