From: Roman Gushchin <roman.gushchin@xxxxxxxxx>
Subject: mm: shrinkers: fix build warnings
Add __printf(a, b) attributes to shrinker functions taking shrinker
name as an argument to avoid compiler warnings like:
mm/shrinker_debug.c:143:9: warning: function 'shrinker_debugfs_rename'
might be a candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
mm/shrinker_debug.c:217:9: warning: function 'shrinker_debugfs_rename'
might be a candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
mm/vmscan.c:637:9: warning: function 'prealloc_shrinker' might be a
candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
mm/vmscan.c:642:9: warning: function 'prealloc_shrinker' might be a
candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
mm/vmscan.c:697:9: warning: function 'register_shrinker' might be a
candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
mm/vmscan.c:702:9: warning: function 'register_shrinker' might be a
candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
