[Gluster-devel] ioctl support in GlusterFS

[Bharata B Rao]

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.
Regards,
Bharata.
