From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This is an updated series for adding tag pre-allocation support of target fabric descriptor memory, utilizing Kent's latest in-flight per-cpu ida bits here: [PATCH v3] lib/idr.c rewrite, percpu ida/tag allocator http://marc.info/?l=linux-kernel&m=137308733526328&w=2 Patch #1 includes target-core setup of

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
