Hi all, Today's linux-next merge of the block tree got a conflict in: fs/ext4/super.c between commit: ffea255f4052 ("ext4: Fix reusing stale buffer heads from last failed mounting") from the ext4 tree and commits: 2736e8eeb0cc ("block: use the holder as indication for exclusive opens") a42fb5a75ccc ("ext4: Fix warning in blkdev_put()") from the block tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc fs/ext4/super.c index b3819e70093e,64342adcd679..000000000000 --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@@ -1128,13 -1133,7 +1133,13 @@@ static void ext4_blkdev_remove(struct e struct block_device *bdev; bdev = sbi->s_journal_bdev; if (bdev) { + /* + * Invalidate the journal device's buffers.
