Subject[PATCH 05/22] staging: lustre: llite: handle xattr cache refill race
Date
From: "John L. Hammond" <john.hammond@intel.com>

In ll_xattr_cache_refill() if the xattr cache was invalid (and no
request was sent) then return -EAGAIN so that ll_getxattr_common()
caller will fetch the xattr from the MDT.
