Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs update from Al Viro: - misc stable fixes - trivial kernel-doc and comment fixups - remove never-used block_page_mkwrite() wrapper function, and rename the function that is _actually_ used to not have double underscores. * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: 9p: cache.h: Add #define of include guard vfs: remove stale comment in inode_operations vfs: remove unused wrapper block_page_mkwrite() binfmt_elf: Correct `arch_check_elf's description fs: fix writeback.c kernel-doc warnings fs: fix inode.c kernel-doc warning fs/pipe.c: return error code rather than 0 in pipe_write() fs/pipe.c: preserve alloc_file() error code binfmt_elf: Don't clobber passed executable's file header FS-Cache: Handle a write to the page immediately beyond the EOF marker cachefiles: perform test on s_blocksize when opening cache file. FS-Cache: Don't override netfs's primary_index if registering failed FS-Cache: Increase reference of parent after registering, netfs success debugfs: fix refcount imbalance in start_creating
