Pull overlayfs updates from Miklos Szeredi: "This work from Amir adds NFS export capability to overlayfs. NFS exporting an overlay filesystem is a challange because we want to keep track of any copy-up of a file or directory between encoding the file handle and decoding it. This is achieved by indexing copied up objects by lower layer file handle. The index is already used for hard links, this patchset extends the use to NFS file handle decoding" * 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: (51 commits) ovl: check ERR_PTR() return value from ovl_encode_fh() ovl: fix regression in fsnotify of overlay merge dir ovl: wire up NFS export operations ovl: lookup indexed ancestor of lower dir ovl: lookup connected ancestor of dir in inode cache ovl: hash non-indexed dir by upper inode for NFS export ovl: decode pure lower dir file handles ovl: decode indexed dir file handles ovl: decode lower file handles of unlinked but open files ovl: decode indexed non-dir file handles ovl: decode lower non-dir file handles ovl: encode lower file handles ovl: copy up before encoding non-connectable dir file handle ovl: encode non-indexed upper file handles ovl: decode connected upper dir file handles ovl: decode pure upper file handles ovl: encode pure upper file handles ovl: document NFS export vfs: factor out helpers d_instantiate_anon() and d_alloc_anon() ovl: store 'has_upper' and 'opaque' as bit flags ... |
