Hi, As support for SCSI offloads like WRITE SAME and UNMAP is being made available on Linux via ioctls (BLKZEROUT, BLKDISCARD), the same can be exploited from GlusterFS for virtualization usecase if GlusterFS also supported ioctl as an FOP. Is there any historical reason for GlusterFS not supporting ioctl ? I gathered from my brief discussion over irc that there isn't any particular reason for this, but wanted to ask the developer community before we start working on adding ioctl FOP in GlusterFS.
