fs/Kconfig: Fix compile error for romfs
There are some compile errors reported by kernel test robot: arm-linux-gnueabi-ld: fs/romfs/storage.o: in function `romfs_dev_read': storage.c:(.text+0x64): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x9c): undefined reference to `__bread_gfp' arm-linux-gnueabi-ld: fs/romfs/storage.o: in function `romfs_dev_strnlen': storage.c:(.text+0x128): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x16c): undefined reference to `__bread_gfp' arm-linux-gnueabi-ld: fs/romfs/storage.o: in function `romfs_dev_strcmp': storage.c:(.text+0x22c): undefined reference to `__bread_gfp' arm-linux-gnueabi-ld: storage.c:(.text+0x27c): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x2a8): undefined reference to `__bread_gfp' arm-linux-gnueabi-ld: storage.c:(.text+0x2bc): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x2d4): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x2f4): undefined reference to `__brelse' arm-linux-gnueabi-ld: storage.c:(.text+0x304): undefined reference to `__brelse' The reason for the problem is that the commit "925c86a19bac" ("fs: add CONFIG_BUFFER_HEAD") has added a new config "CONFIG_BUFFER_HEAD" that controls building the buffer_head code, and romfs needs to use the buffer_head API, but no corresponding config has beed added. Select the config "CONFIG_BUFFER_HEAD" in romfs Kconfig to resolve the problem.
