Hey, This is the second resend of this patchset. I'm not sure whether it has simply been overlooked but the number of people get_maintainer.pl was rather small and seemed a little random so I added Linus and Christoph, two people I know that do look at VFS stuff at least from time to time, although they weren't listed by get_maintainer.pl. I hope that's ok.
This little series - unifies the definition of constants in statfs.h and fs.h *Note, that Andreas has expressed doubts whether this unification is useful. Please see https://lkml.org/lkml/2018/4/13/571 . I still think it is but I'm happy to drop these two patches if others agree.* - extends statfs to handle mount propagation. This will let userspace easily query a given mountpoint for MS_UNBINDABLE, MS_SHARED, MS_PRIVATE and MS_SLAVE without always having to do costly parsing of /proc/<pid>/mountinfo. To this end the flags: - ST_UNBINDABLE - ST_SHARED - ST_PRIVATE - ST_SLAVE are added. They have the same value as their MS_* counterparts. Thanks!
