The shrinker.h header depends on a user including other headers before
it for types used by shrinker.h. Fix this by including the appropriate
headers in shrinker.h.
./include/linux/shrinker.h:13:9: error: unknown type name ‘gfp_t’
13 | gfp_t gfp_mask;
| ^~~~~
./include/linux/shrinker.h:71:26: error: field ‘list’ has incomplete type
71 | struct list_head list;
| ^~~~
./include/linux/shrinker.h:82:9: error: unknown type name ‘atomic_long_t’
82 | atomic_long_t *nr_deferred;
|
Fixes: 83aeeada7c69 ("vmscan: use atomic-long for shrinker batching")
Fixes: b0d40c92adaf ("superblock: introduce per-sb cache shrinker infrastructure")
