Subject: I/O topology fixes for big physical block size
Date: Mon, 27 Sep 2010 12:41:02 -0400 [thread overview]
Message-ID: <1285605664-27027-1-git-send-email-martin.petersen@oracle.com> (raw)
Mike Snitzer reported that he has access to a device that supports thin
provisioning but does not use the Block Limits VPD page to indicate
discard granularity. Instead it reports a huge (1MB) physical block
size. That caused a bit of fallout in the topology stack which assumed a
physical block size of 4KiB or less.
[PATCH 1/2] block: Ensure physical block size is unsigned int
[PATCH 2/2] sd: Fix overflow with big physical blocks
