Way back in 3.2 time-frame we worked out some of these patches and how to improve the code. I don't think I had posted them after we chatted about what to do or how to do it... Either way, posting them here to kick-start the conversation and see if we can improve these patches some more. I've been running with these patches for some time now so I am quite confident that I got the 32-bit to 64-bit structure padding worked out. (Ran it with old guests/new guests/32-bit/64-bit/Linux/Windows combination. Around 18 different scenarios). Konrad Rzeszutek Wilk (3): xen/blk[front|back]: Squash blkif_request_rw and blkif_request_discard together xen/blk[front|back]: Enhance discard support with secure erasing support. xen/blkback: Move processing of BLKIF_OP_DISCARD from dispatch_rw_block_io Li Dongyang (1): xen-blkback: convert hole punching to discard request on loop devices drivers/block/xen-blkback/blkback.c | 84 ++++++++++++++-------------------- drivers/block/xen-blkback/common.h | 67 ++++++++++++++++------------ drivers/block/xen-blkback/xenbus.c | 12 +++++ drivers/block/xen-blkfront.c | 77 +++++++++++++++++++++----------- include/xen/interface/io/blkif.h | 40 ++++++++++++++--- 5 files changed, 169 insertions(+), 111 deletions(-) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
