Subject: support ranges TRIM for libata
Date: Mon, 20 Mar 2017 16:43:12 -0400 [thread overview]
Message-ID: <20170320204319.12628-1-hch@lst.de> (raw)
This series implements rangeѕ discard for ATA SSDs. Compared to the
initial NVMe support there are two things that complicate the ATA
support:
- ATA only suports 16-bit long ranges
- the whole mess of generating a SCSI command first and then
translating it to an ATA one.
This series adds support for limited range size to the block layer,
and stops translating discard commands - instead we add a new
Vendor Specific SCSI command that contains the TRIM payload when
the device asks for it.
