Subject: Initialize the /dev/splatctl device buffer
X-Git-Tag: spl-0.5.0~30
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1a73940d39f07332921a7f78eaca9bd9266c5c7a;p=spl

Initialize the /dev/splatctl device buffer

On open() and initialize the buffer with the SPL version string.  The
user space splat utility expects to find the SPL version string when
it opens and reads from /dev/splatctl.
