| |
Hi Al,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-viro
This has an assortment of fixes and cleanups for overlayfs.
It also touches the VFS:
- add the vfs_get_link() helper for calling i_op->get_link(); - fix mnt_want_write_file() to freeze protect the underlying sb instead of overlay sb; - allow vfs_clone_file_range() to be called by overlayfs.
None of the above should have any effect on filesystems other than overlayfs.
Thanks, Miklos
--- Amir Goldstein (3): vfs: allow vfs_clone_file_range() across mount points vfs: call vfs_clone_file_range() under mnt_want_write() ovl: use vfs_clone_file_range() for copy up if possible
Miklos Szeredi (8): ovl: copy_up_xattr(): use strnlen ovl: lookup: do getxattr with mounter's permission vfs: mnt_want_write_file() should freeze protect underlying sb ovl: make directory ino/dev numbers stable ovl: explain error values when removing acl from workdir ovl: use generic_readlink vfs: add vfs_get_link() helper ovl: use vfs_get_link()
