xentop reporting zero written sectors
Just moving a chunk of files from one filesysstem on xvba to another on xvdb, and was monitoring with xentop as it was taking longer than expected. The VBD_RD and VBD_WR counters were both clocking-up as expected, as was the VBD_RSECT counter, but the VBD_WSECT counter was stuck on zero, I toggled on the individual VBD device counters and these showed the same (with the RD and WR counters

[blkback] blkback statistic counters are signed values
...nto an unsigned long long. That value is exposed by blkback, and among other stat counters, it''s a signed integer: drivers/block/xen-blkback/common.h struct xen_blkif { ... int st_rd_req; int st_wr_req; int st_oo_req; int st_f_req; int st_ds_req; int st_rd_sect; int st_wr_sect; I don''t think these values should be negative ever, but when they overflow (which happens eventually), they do, and this leads to bad conversion in xentop. I think the best solution would be to change the above mentioned values to unsigned long long as well. Any comments on that? Re...

[PATCH] xen-blk[front|back] FUA additions.
I am proposing these two patches for 3.2. They allow the backend to process the REQ_FUA request as well. Previous to these patches it only did REQ_FLUSH. There is also a bug-fix for the logic of how barrier/flushes were handled. The patches are based on a branch which also has ''feature-discard'' patches, so they won''t apply nativly on top of 3.1-rc5. Please review and

[PATCH V4 0/3] xen-blkfront/blkback discard support
Dear list, This is the V4 of the trim support for xen-blkfront/blkback, Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all "trim" stuffs in the patches, and use "discard" instead. Also we updated the helpers of blkif_x86_{32|64}_request or we will meet problems using a non-native protocol. And this patch has been tested with both SSD and raw file, with SSD we will

xenpaging fixes for kernel and hypervisor
Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.
