dax, xfs, ext4: compile out iomap-dax paths in the FS_DAX=n case
Tetsuo reports:
fs/built-in.o: In function `xfs_file_iomap_end':
xfs_iomap.c:(.text+0xe0ef9): undefined reference to `put_dax'
fs/built-in.o: In function `xfs_file_iomap_begin':
xfs_iomap.c:(.text+0xe1a7f): undefined reference to `dax_get_by_host'
make: *** [vmlinux] Error 1
$ grep DAX .config
CONFIG_DAX=m
# CONFIG_DEV_DAX is not set
# CONFIG_FS_DAX is not set
When FS_DAX=n we can/must throw away the dax code in filesystems.
Implement 'fs_' versions of dax_get_by_host() and put_dax() that are
nops in the FS_DAX=n case.
