Hello Tomas,
Yes, you are right. The mentioned comment is right for some cases where as in
some cases it should actually be the size of response buffer instead of request
buffer.
To "get logical device name", it request size of response buffer instead of
size of the request.
Thanks,

uh - we're flagging issues with in a patch explanation (such as 2 spaces
after a period) and not something in the patch itself ??
I'm not going to revise patches for minor typos or styles disagreements
in patch descriptions.

Sebastian,
Re: more than 1 space between a type declaration and a variable name - I
do not believe that's a hard requirement. It fully passes checkpatch.
Yes, consistent style use (aligning all variable names at same offset,
or always 1) would be good - but code has been there so long with

Feedback from an RCU expert (which I'm not) would be appreciated here.
But my understanding is that lockless_dereference(p) should be used for

Hi all,
Here is v2 series with HCH's recent changes to go ahead and drop
all se_port + t10_alua_tg_pt_gp_member usage within target-core in
favor of direct se_lun pointer dereference.
This includes the original patch + minor fixes, along with two other
improvements for

This patch eliminates all se_port + t10_alua_tg_pt_gp_member usage,
and converts current users to direct se_lun pointer dereference.
This includes the removal of core_export_port(), core_release_port()

Instead, use the existing se_wwn->wwn_tf->tf_ops pointer to ensure
