Some time ago I proposed to discuss how to improve discard support
during the LSF/MM (http://thread.gmane.org/gmane.linux.scsi/110048).
I would appreciate it if this would be added to the LSF/MM agenda
since there has been no progress yet for the patch series I posted in
December 2015.
Well, adding a cc to the lsf@ list to interest the attendees might have
been a good idea.
The basic problem with this topic is that it didn't really garner any
interest when you proposed it. It also really just looks like there's
nothing to discuss: you just propose the unifying patch and people
discuss and modify that and it either gets accepted or not depending on
the level of the objections.
Hello James,
There is something that should be discussed further, namely what the
behavior of the BLKDISCARD and BLKSECDISCARD ioctls should be if the
start and/or end sectors are not aligned on a discard boundary. Should
such requests fail with an error code, should the non-aligned head and
tail be zeroed or should the non-aligned parts be left unmodified?
Thanks,
Bart.
