Jffs2: systemd-journald fails to open log files on jffs2

[Frank Mori Hess]

Hi, I have systemd-journald spewing EINVAL errors on a 4.1.33 kernel
when it tries to
open persistent journal files on jffs2, for example:

systemd-journald[766]: Failed to open system journal: Invalid argument

I traced this back to a failing mmap call which was attempting to do a
writable mmap with MAP_SHARED.  Are there any plans for jffs2 to
support such mappings, or is the answer just to dump jffs2 and move on
to ubifs?
