These patches contain the beginnings of discard (a.k.a. trim or unmap) support. This will allow us to change virt-sparsify to work on disk images in-place (instead of using slow & inefficient copying). The approach used is to add an optional 'discard' parameter to add-drive. It has 3 possible settings: - 'disable' : the...

Hey guys, Pasi mentioned on Li''s (and Owen''s) patches which provide TRIM/UNMAP support to the Linux backend/frontend that: " Isn''t the generic name for this functionality "discard" in Linux? and "trim" being the ATA specific discard-implementation, and "scsi unmap" the SAS/SCSI specific discard-implementation? Just wondering.. " and it sounds right to me. The problem is of course that the ''feature-trim'' is already in...

This set of patches: - Adds new APIs to support discard in libguestfs. - Adds discard support to virt-format. - Adds discard support to virt-sysprep. - Implements virt-sparsify --in-place. This is now working, after fixing the rather stupid bug in fstrim. I've pushed the ones which were ACKed previously + the fstrim fix. Rich.

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 forward the discar...
