Subject: [PATCH 0/6 RESEND] statfs: handle mount propagation

Hey,

This is a resend of this to CC more people and because it seems to have
gotten lost in the prior merge window. I should've sent it afterwards
right away.

This series:
- unifies the definition of constants in statfs.h and fs.h
  Please note the comments by Greg and others on this part:
  https://patchwork.kernel.org/patch/10340403/
  https://patchwork.kernel.org/patch/10340379/
  I haven't yet changed the fs.h and statfs.h header changes to not
  bitshifts. I wanted to wait what Al would think of it.
- 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.

Thanks!
Christian

Christian Brauner (6):
  fs: use << for MS_* flags
  statfs: use << to align with fs header
  statfs: add ST_UNBINDABLE
  statfs: add ST_SHARED
  statfs: add ST_PRIVATE
  statfs: add ST_SLAVE
