4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>
commit 803c00123a8012b3a283c0530910653973ef6d8f upstream.
Failing to allocate an inode for child means that cache for *parent* is
incompletely populated. So it's parent directory inode ('dir') that
needs NCPI_DIR_CACHE flag removed, *not* the child inode ('inode', which
is what we'd failed to allocate in the first place).
Fucked-up-in: commit 5e993e25 ("ncpfs: get rid of d_validate() nonsense")
