[PATCH 18/41] staging: lustre: llite: Report first encountered error

From: James Simmons
Date: Sun Oct 02 2016 - 22:30:42 EST


From: Henri Doreau <henri.doreau@xxxxxx>

Failures in ll_ioc_copy_{start,end} are reported to coordinator.
The return code delivered to the caller should indicate what this
error was, not whether coordinator was successfully notified.
