Al and Linus, Please consider overlayfs for inclusion into 3.10. It's included in Ubuntu and openSUSE, used by OpenWrt and various other projects. I regularly get emails asking when it will be included in mainline. Git tree is here: git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs.v16 Thanks, Miklos --- Andy Whitcroft (3): overlayfs-add-statfs-support ovl-switch-to-inode_permission overlayfs-copy-up-i_uid-i_gid-from-the-underlying-inode Erez Zadok (1): overlayfs-implement-show_options Miklos Szeredi (6): vfs-add-i_op-dentry_open vfs-export-do_splice_direct-to-modules vfs-introduce-clone_private_mount overlay filesystem fs-limit-filesystem-stacking-depth vfs-export-inode_permission-to-modules Neil Brown (1): overlay-overlay-filesystem-documentation Robin Dong (2): overlayfs-fix-possible-leak-in-ovl_new_inode overlayfs-create-new-inode-in-ovl_link --- Documentation/filesystems/Locking | 2 + Documentation/filesystems/overlayfs.txt | 199 +++++++++ Documentation/filesystems/vfs.txt | 7 + MAINTAINERS | 7 + fs/Kconfig | 1 + fs/Makefile | 1 + fs/ecryptfs/main.c | 7 + fs/internal.h | 5 - fs/namei.c | 10 +- fs/namespace.c | 18 + fs/open.c | 23 +- fs/overlayfs/Kconfig | 4 + fs/overlayfs/Makefile | 7 + fs/overlayfs/copy_up.c | 385 +++++++++++++++++ fs/overlayfs/dir.c | 604 +++++++++++++++++++++++++++ fs/overlayfs/inode.c | 372 +++++++++++++++++ fs/overlayfs/overlayfs.h | 70 ++++ fs/overlayfs/readdir.c | 566 +++++++++++++++++++++++++ fs/overlayfs/super.c | 685 +++++++++++++++++++++++++++++++ fs/splice.c | 1 + include/linux/fs.h | 14 + include/linux/mount.h | 3 + 22 files changed, 2981 insertions(+), 10 deletions(-) create mode 100644 Documentation/filesystems/overlayfs.txt create mode 100644 fs/overlayfs/Kconfig create mode 100644 fs/overlayfs/Makefile create mode 100644 fs/overlayfs/copy_up.c create mode 100644 fs/overlayfs/dir.c create mode 100644 fs/overlayfs/inode.c create mode 100644 fs/overlayfs/overlayfs.h create mode 100644 fs/overlayfs/readdir.c create mode 100644 fs/overlayfs/super.c -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
