Subject: autofs: make autofs4 and autofs mutually exclusive
The autofs4 implementation is just a redirect to autofs now, but that
also means we can't have both built into the same kernel:
fs/autofs/inode.o: In function `autofs_new_ino':
inode.c:(.text+0x1b8): multiple definition of `autofs_new_ino'
fs/autofs/inode.o:inode.c:(.text+0x1b8): first defined here
fs/autofs/inode.o: In function `autofs_clean_ino':
inode.c:(.text+0x288): multiple definition of `autofs_clean_ino'
There is also a problem with trying to build both in parallel, which
leads to two 'make' processes writing to the same fs/autofs/.*.o.cmd
file, causing corruption that manifests like
fs/autofs4/../autofs/.expire.o.cmd:679: *** missing separator. Stop.
Making AUTOFS4_FS depend on AUTOFS_FS being disabled should avoid all
configurations that run into either issue.
