From 7c9d8d0c41b3e24473ac7648a7fc2d644ccf08ff Mon Sep 17 00:00:00 2001 From: "Bryant G. Ly" Date: Mon, 9 Jan 2017 10:21:20 -0600 Subject: [PATCH] ibmvscsis: Fix srp_transfer_data fail return code If srp_transfer_data fails within ibmvscsis_write_pending, then the most likely scenario is that the client timed out the op and removed the TCE mapping. Thus it will loop forever retrying the op that is pretty much guaranteed to fail forever. A better return code would be EIO instead of EAGAIN.
