Subject[PATCH v4 0/3] libfs,xenfs: replace /proc/xen/xenbus with a symlink
Date
Using /proc/xen/xenbus can cause deadlocks on the atomic file position
mutex since this file should behave like a character device and not a
regular file. This is easiest to achive by making it a symlink to the
existing /dev/xen/xenbus device.

This requires extending simple_fill_super() to add symlinks as well as
regular files.

David

Changes in v4:
- Switch on file type in simple_fill_super()
- Make xen_xenus_fops and xen_privcmd_fops static
- Rebased on v4.9-rc2.
- Add patch from Seth for namespace support.

Changes in v3:
- Rebased on v4.7-rc5.

Changes in v2:
