linux-next: build failure after merge of the akpm tree

Hi all, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this: fs/gfs2/bmap.c: In function 'sweep_bh_for_rgrps': fs/gfs2/bmap.c:1075:5: error: 'CURRENT_TIME' undeclared (first use in this function) CURRENT_TIME; ^ fs/gfs2/bmap.c:1075:5: note:

[PATCH 00/11] block: assorted cleanup for bio splitting and cloning.

This series contains more work towards getting rid of the bioset work queues and generally improving the splitting and cloning of bios. The first three patches are similar to ones that I sent previously. They have been rebased on the current block for-next tree and improved a little.

[PATCH 08/11] xen-blkfront: remove bio splitting.

bios that are re-submitted will pass through blk_queue_split() when blk_queue_bio() is called, and this will split the bio if necessary. There is no longer any need to do this splitting in xen-blkfront. Signed-off-by: NeilBrown --- drivers/block/xen-blkfront.c | 54
