Hi Andrew, After merging the akpm tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: fs/jfs/jfs_logmgr.c: In function 'lbmRead': fs/jfs/jfs_logmgr.c:2015:3: error: too few arguments to function 'lbmIODone' lbmIODone(bio, 0); ^ fs/jfs/jfs_logmgr.c:194:21: note: declared here static bio_end_io_t lbmIODone; ^ Caused by commit daf8a85f357a ("block: prep work for batch completion") from the akpm tree interacting with commit 95bbb82f60c8 ("fs/jfs: Add check if journaling to disk has been disabled in lbmRead()") from the jfs tree. I applied the following fix up patch and can carry it as necessary.
