Subject: libata: remove the global response buffer
Date: Tue, 10 Jan 2017 09:41:42 +0100 [thread overview]
Message-ID: <1484037708-654-1-git-send-email-hch@lst.de> (raw)
Avoid the need for a global 4k buffer by allocating no response buffer
for commands that don't return data, a small on-stack one for the ATAPI
fixup, or a kmalloced one for all other emulated commands.
