Subject: please revert the UFS HPB support
Date: Thu, 21 Oct 2021 16:42:10 +0200	[thread overview]
Message-ID: <20211021144210.GA28195@lst.de> (raw)

Hi Martin,

I just noticed the UFS HPB support landed in 5.15, and just as
before it is completely broken by allocating another request on
the same device and then reinserting it in the queue.  It is bad
enough that we have to live with blk_insert_cloned_request for
dm-mpath, but this is too big of an API abuse to make it into
a release.  We need to drop this code ASAP, and I can prepare
a patch for that.
