Hi!
Do you mean calling sys_sync() after the userspace has been frozen
may not be sufficient?
In most cases it probably is, but sys_sync() doesn't provide any
guarantees that the filesystem is not being used or written to after
it completes. Given that every so often I hear about an XFS filesystem
that was corrupted by suspend, I don't think this is sufficient...
Userspace is frozen. There's noone that can write to the XFS
filesystem.
Pavel
