Currently, we don't have a consistent story around logging when an EXPERIMENTAL feature gets turned on at runtime -- online fsck and shrink log a message once per day across all mounts, and the recently merged LARP mode only ever does it once per insmod cycle or reboot. Because EXPERIMENTAL tags are supposed to go away eventually, convert the existing daily warnings into state flags that travel with the mount, and warn once per mount. Making this an opstate flag means that we'll be able to capture the experimental usage in the ftrace output too. Signed-off-by: Darrick J.
