[PATCH] scsi: ufs: mark HPB support as BROKEN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The HPB support added this merge window is fundanetally flawed as it
uses blk_insert_cloned_request to insert a cloned request onto the same
queue as the one that the original request came from, leading to all
kinds of issues in blk-mq accounting (in addition to this API being
a special case for dm-mpath that should not see other users).

Mark is as BROKEN as the non-intrusive alternative to a last minute
large scale revert.

feature")
