Subject: [PATCH] mm/slub.c: use 'unsigned long' instead of 'int' for variable 'slub_debug'
Date: Fri, 12 Jul 2013 09:43:31 +0800 [thread overview]
Message-ID: <51DF5F43.3080408@asianux.com> (raw)
Since all values which can be assigned to 'slub_debug' are 'unsigned
long', recommend also to define 'slub_debug' as 'unsigned long' to
match the type precisely
e.g DEBUG_DEFAULT_FLAGS, SLAB_TRACE, SLAB_FAILSLAB ...
