Subject: ocfs2: adjust minlen with discard_granularity in the FITRIM ioctl
Adjust minlen with discard_granularity for FITRIM ioctl(2) if the given
minimum size in bytes is less than it because, discard granularity is used
to tell us that the minimum size of extent that can be discarded by the
storage device.
This is inspired by ext4 commit 5c2ed62fd4 ("ext4: Adjust minlen with
discard_granularity in the FITRIM ioctl") from Lukas Czerner.
