From: Steven Whitehouse Date: Tue, 4 Nov 2008 10:05:22 +0000 (+0000) Subject: GFS2: Banish struct gfs2_dinode_host X-Git-Tag: firefly_0821_release~16399^2~18 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=383f01fbf4a701b73f5e35ea805ed1700b4b4db9;p=firefly-linux-kernel-4.4.55.git GFS2: Banish struct gfs2_dinode_host The final field in gfs2_dinode_host was the i_flags field. Thats renamed to i_diskflags in order to avoid confusion with the existing inode flags, and moved into the inode proper at a suitable location to avoid creating a "hole". At that point struct gfs2_dinode_host is no longer needed and as promised (quite some time ago!) it can now be removed completely.
