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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/block/rbd.c: In function 'wake_lock_waiters':
drivers/block/rbd.c:3933:2: error: implicit declaration of function 'lockdep_assert_held_exclusive'; did you mean 'lockdep_assert_held_write'? [-Werror=implicit-function-declaration]
  lockdep_assert_held_exclusive(&rbd_dev->lock_rwsem);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  lockdep_assert_held_write

Caused by commit

  9ffbe8ac05db ("locking/lockdep: Rename lockdep_assert_held_exclusive() -> lockdep_assert_held_write()")

interacting with commits

  637cd060537d ("rbd: new exclusive lock wait/wake code")
  a2b1da09793d ("rbd: lock should be quiesced on reacquire")

from the ceph tree.

I have added the following merge fix patch for today.

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Tue, 9 Jul 2019 16:46:12 +1000
Subject: [PATCH] rbd: fix up for lockdep_assert_held_exclusive rename
