Subject: [SCSI] libiscsi, iscsi class: set tmf to a safe default and export in sysfs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4cd49ea1330c946db00a28819b766062716aa857;p=linux-beck.git

[SCSI] libiscsi, iscsi class: set tmf to a safe default and export in sysfs

Older tools will not be setting the tmf time outs since they
did not exists, so set them to a safe default.

And export abort and lu reset timeout values in sysfs.
