The new shrinker API as of Linux 3.12 modifies "struct shrinker" by replacing the @shrink callback with the pair of @count_objects and @scan_objects. It also requires the return value of @count_objects to return the number of objects actually freed whereas the previous @shrink callback returned the number of remaining freeable objects. This patch adds support for the new @scan_objects return value semantics. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>

@behlendorf behlendorf/zfs@6813624 also LGTM (in conjunction with behlendorf/spl@f9757c6). Again, thanks for the cleanup. |
