Re: [PATCH 14/17] scsi_dh_alua: Use workqueue for RTPG

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



So how about the following idea for GTPG and STPG handling:

 - we keep a single thread workqueue, but per target group instead
   of global to avoid concurrency issues hitting us too badly, after
   all workqueues are cheap these days.
 - GTPG keeps the per-group work_item, but instead of the separate
   lsit for STPG we just add the work item to the alua_queue_data
   structure, which at the point might also get a new name relecting
   the use a bit better.  STPG remains synchronous.

Btw, any chance to also publish a git tree to make reviewing easier?
