Hey, This little series - unifies the definition of constants in statfs.h and fs.h - 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. The patchset was made against Al's vfs/for-next tree but they also apply cleanly against current linus/master. So if they are deemed suitable for inclusion in the current release that should work too. Thanks!
