Subject: [PATCH v5 0/2] xenfs: xenbus and container related bug fixes
Date: Mon, 14 Nov 2016 11:12:54 +0000 [thread overview]
Message-ID: <1479121976-26568-1-git-send-email-david.vrabel@citrix.com> (raw)
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 clearing FMODE_ATOMIC_POS.
David
Changes in v5:
- Clear FMODE_ATOMIC_POS instead of using symlinks.
Changes in v4:

- 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:
