[LU-5642] getxattr failing with EIO

Tue, 14 Oct 2014 01:45:28 +0000

getxattr() calls occasionally fail with EIO. We believe that this is due to a race between concurrent calls on the same file (see ll_xattr_cache_refill):

/* Matched but no cache? Cancelled on error by a parallel refill. */
if (unlikely(req == NULL)) {
CDEBUG(D_CACHE, "cancelled by a parallel getxattr\n");
GOTO(out_maybe_drop, rc = -EIO);
}

This should be adjusted so that both calls end consistenty.
