Subject: [PATCH] ramfs: nommu: Statize ramfs_nommu_get_unmapped_area and ramfs_nommu_mmap
Date: Wed, 20 Nov 2013 10:35:40 +0800 [thread overview]
Message-ID: <1384914940.14597.2.camel@phoenix> (raw)
Since commit 853ac43ab194f "shmem: unify regular and tiny shmem",
ramfs_nommu_get_unmapped_area() and ramfs_nommu_mmap() are not directly
referenced outside of file-nommu.c. Thus make them static.
