Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs fixes from Al Viro: "Assorted fixes all over the place" * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: aio: fix io_destroy(2) vs. lookup_ioctx() race ext2: fix a block leak nfsd: vfs_mkdir() might succeed leaving dentry negative unhashed cachefiles: vfs_mkdir() might succeed leaving dentry negative unhashed unfuck sysfs_mount() kernfs: deal with kernfs_fill_super() failures cramfs: Fix IS_ENABLED typo befs_lookup(): use d_splice_alias() affs_lookup: switch to d_splice_alias() affs_lookup(): close a race with affs_remove_link() fix breakage caused by d_find_alias() semantics change fs: don't scan the inode cache before SB_BORN is set do d_instantiate/unlock_new_inode combinations safely iov_iter: fix memory leak in pipe_get_pages_alloc() iov_iter: fix return type of __pipe_get_pages()
