[PATCH] dm: suspend: parameter change
Change the interface of dm_suspend() so that we can pass several options
without increasing the number of parameters. The existing 'do_lockfs' integer
parameter is replaced by a flag DM_SUSPEND_LOCKFS_FLAG.
There is no functional change to the code.
Test results:
I have tested 'dmsetup suspend' command with/without the '--nolockfs'
option and confirmed the do_lockfs value is correctly set.
