Subject: [GFS2] Move gfs2_logd into log.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ec69b188837a347769e187997d040e84a683b38a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[GFS2] Move gfs2_logd into log.c

This means that we can mark gfs2_ail1_empty static and prepares
the way for further changes.
