Subject: [PATCH 0/3] mmap vs NFS
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

Currently there is an AB-BA deadlock in NFS mmap.

nfs_file_mmap() can take i_mutex, while holding mmap_sem, whereas the regular
locking order is the other way around.

This patch-set attempts to solve this issue.
