Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull more VFS bits from Al Viro: "Unfortunately, it looks like xattr series will have to wait until the next cycle ;-/ This pile contains 9p cleanups and fixes (races in v9fs_fid_add() etc), fixup for nommu breakage in shmem.c, several cleanups and a bit more file_inode() work" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: constify path_get/path_put and fs_struct.c stuff fix nommu breakage in shmem.c cache the value of file_inode() in struct file 9p: if v9fs_fid_lookup() gets to asking server, it'd better have hashed dentry 9p: make sure ->lookup() adds fid to the right dentry 9p: untangle ->lookup() a bit 9p: double iput() in ->lookup() if d_materialise_unique() fails 9p: v9fs_fid_add() can't fail now v9fs: get rid of v9fs_dentry 9p: turn fid->dlist into hlist 9p: don't bother with private lock in ->d_fsdata; dentry->d_lock will do just fine more file_inode() open-coded instances selinux: opened file can't have NULL or negative ->f_path.dentry (In the meantime, the hlist traversal macros have changed, so this required a semantic conflict fixup for the newly hlistified fid->dlist)
