[PATCH] x86-64: Shut up warnings for vfat compat ioctls on other file systems (2724b6db) · Commits · 戴 / test

vfat implements compat handlers for these ioctls, but when they were executed on other file systems the kernel would still complain about an unknown compat ioctl. Just declare them as compatible and let them be rejected when not needed by the normal path. This makes wine runs a lot quieter Signed-off-by:
