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 FS/block layer but it requires 512 byte alignment, so depending on the FS/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. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
