Subject: [PATCH 0/3] vhost-scsi: Fix IO hangs when using windows
Date: Wed, 24 May 2023 18:34:04 -0500 [thread overview]
Message-ID: <20230524233407.41432-1-michael.christie@oracle.com> (raw)
The following patches were made over Linus's tree and fix an issue
where windows guests will send iovecs with offset/lengths that result
in IOs that are not aligned to 512. The LIO layer will then send them
to Linux's block layer but it requires 512 byte alignment, so depending
on the block driver being used we will get IO errors or hung IO.
The following patches have vhost-scsi detect when windows sends these
IOs and copy them to a bounce buffer. It then does some cleanup in
the related code.
