parentNFS: Allow optimisation of lseek(fd, SEEK_CUR, 0) on directories (diff)
pNFS: Parse the results of layoutget on open even if permissions checks fail
Even if the results of the permissions checks failed, we should parse the results of the layout on open call so that we can return the layout if required. Note that we also want to ignore the sequence counter for whether or not a layout recall occurred. If the recall pertained to our OPEN, then the callback will know, and will attempt to wait for us to finih processing anyway. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
