Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull VFS patches (part 1) from Al Viro: "The major change in this pile is ->readdir() replacement with ->iterate(), dealing with ->f_pos races in ->readdir() instances for good. There's a lot more, but I'd prefer to split the pull request into several stages and this is the first obvious cutoff point." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (67 commits) [readdir] constify ->actor [readdir] ->readdir() is gone [readdir] convert ecryptfs [readdir] convert coda [readdir] convert ocfs2 [readdir] convert fatfs [readdir] convert xfs [readdir] convert btrfs [readdir] convert hostfs [readdir] convert afs [readdir] convert ncpfs [readdir] convert hfsplus [readdir] convert hfs [readdir] convert befs [readdir] convert cifs [readdir] convert freevxfs [readdir] convert fuse [readdir] convert hpfs reiserfs: switch reiserfs_readdir_dentry to inode reiserfs: is_privroot_deh() needs only directory inode, actually ...
