| |
Hi Eric,
After merging the userns tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
fs/namespace.c: In function 'detach_mounts': fs/namespace.c:1340:2: error: implicit declaration of function 'br_write_lock' [-Werror=implicit-function-declaration] br_write_lock(&vfsmount_lock); ^ fs/namespace.c:1340:17: error: 'vfsmount_lock' undeclared (first use in this function) br_write_lock(&vfsmount_lock); ^ fs/namespace.c:1340:17: note: each undeclared identifier is reported only once for each function it appears in fs/namespace.c:1345:2: error: implicit declaration of function 'br_write_unlock' [-Werror=implicit-function-declaration] br_write_unlock(&vfsmount_lock); ^
Caused by the interaction between commit d7e58b8abc4f ("vfs: Add a function to lazily unmount all mounts from any dentry. v3") from the userns tree and commit 84550b9356af ("RCU'd vfsmounts") from the vfs tree.
I don't know how to fix this up, so I have just dropped the userns tree for today. I only dropped that tree because it was the latter of the two conflicting trees.
