Hi Andrew,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on gfs2/for-next]
[also build test ERROR on v5.1-rc2 next-20190327]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/Andrew-Price/gfs2-Convert-gfs2-to-fs_context/20190328-005647
base: https://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2.git for-next
These failures are due to the wrong base. The patch was based on David
Howells' mount-api-viro branch and not the gfs2 for-next one.
