[GIT PULL] SCSI fixes for 6.13-rc7

From: James Bottomley
Date: Tue Jan 14 2025 - 13:13:28 EST


One iscsi driver fix and one core fix. The core fix is an important
one because a retry efficiency update is now causing some USB devices
to get the wrong size on discovery (it upset their retry logic for
READ_CAPACITY_16).

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Mike Christie (1):
scsi: core: Fix command pass through retry regression

Xiang Zhang (1):
scsi: iscsi: Fix redundant response for ISCSI_UEVENT_GET_HOST_STATS request
