Hi,

Could anyone advise if there is any plan to push these patches to land
the upstream?

Patch 1/3
http://www.mail-archive.com/linux-scsi@xxxxxxxxxxxxxxx/msg14533.html
Patch 2/3
http://www.mail-archive.com/linux-scsi@xxxxxxxxxxxxxxx/msg14381.html
Patch 3/3
http://www.mail-archive.com/linux-scsi@xxxxxxxxxxxxxxx/msg14398.html


In particular patch 2 and 3 are matching the iscsi_tcp.c values and have
improved the performance that we got. It will be beneficial to include
them into the vanilla kernel.


Hey Or,

These patches look ok except for #1. Did you guys have some weird restrictions? Or did you have some weird restrictions but the iser driver handles it (see iser_data_buf_aligned_len related code). I think instead of 0 you want to set the dma alignment to 4K?
