From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Hi Hannes & Co,
This series adds support for MI_REPORT_TARGET_PGS extended header format
within ALUA target port group infrastructure, and adds 'implict_trans_secs'
tg_pt_gp attribute to set this value individually via configfs for each
/sys/kernel/config/target/core/$HBA/$DEV/alua/$ALUA_TG_PT_GP/ group.
This feature has been on my TODO list for a while, and now that Rob Evers
has posted the scsi_dh_alua.c changes to take advantage of this information
array side, it's now time to get this supported within target-core.
Note so far this has been tested with 'sg_raw a3 2a' on loopback LUNs, and
appears to be working as expected. Please have a look and let me know if you
have any concerns.
Thanks!
