Subject: LU-444 lnet: Add LNetError for S_LND and S_LNET
X-Git-Tag: 2.2.51~34
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=c9866d01d009fedc530fb1842486d556a2b5e067

LU-444 lnet: Add LNetError for S_LND and S_LNET

This changes the console error string for LND and LNET subsystem
messages to LNet or LNetError depending on the severity. This
should make it much easier to figure out where the issues are.
