Is it just me or is there (a lot) more going on here other than
this patch description?
Hello Sagi,
I will make the patch description more detailed. Sorry if some of this
code is hard to follow but that's because of the high level of
concurrency in the SRP target driver. Some time ago I documented how
session management in the SCST ib_srpt driver works. This driver follows
the same model. These notes can be found here:
http://sourceforge.net/p/scst/svn/HEAD/tree/trunk/srpt/session-management.txt.
