Subject: mm: shrinkers: Add missing includes for undeclared types
Date: Mon, 14 Nov 2022 23:59:49 +0000
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;
