Subject: [PATCH] efs: move headers out of include/linux/
Date: Sat, 9 Feb 2008 10:20:20 +0100 [thread overview]
Message-ID: <20080209092020.GA5062@lst.de> (raw)
Merge include/linux/efs_fs{_i,_dir}.h into fs/efs/efs.h. efs_vh.h
remains there because this is the IRIX volume header and shouldn't
really be handled by efs but by the partitioning code. efs_sb.h
remains there for now because it's exported to userspace. Of course
this wrong and aboot should have a copy of it's own, but I'll leave
that to a separate patch to avoid any contention.
