Our internal DGX cluster has run into a few ceph client related issues, which were root caused to be resolved by the following commits:
https://github.com/ceph/ceph-client/commit/f42a774a2123e6b29bb0ca296e166d0f089e9113
https://github.com/ceph/ceph-client/commit/093ea205acd4b047cf5aacabc0c6ffecf198d2a9
Can you please backport these into bionic?

3e1d0452edcee ceph: avoid iput_final() while holding mutex or in dispatch thread
1cf89a8dee5e6 ceph: single workqueue for inode related works |
[Impact]
Deadlock may occur if iput_final() decides to wait for readahead pages
while a lock is held.
In order to resolve this, the following two patches install an
asynchronous "iput" for the ceph inodes so that a hold-and-wait deadlock
doesn't occur. A more detailed example is shown in the original patch:
https://github.com/ceph/ceph-client/commit/093ea205acd4b047cf5aacabc0c6ffecf198d2a9
Requested patches:
3e1d0452edcee ceph: avoid iput_final() while holding mutex or in dispatch thread
1cf89a8dee5e6 ceph: single workqueue for inode related works
[Test Case]
These changes were tested by the original requester with positive results over a few days in their own environment where they first experienced the regression. They have determined they are no longer experiencing the regression with this patch set applied to a test kernel.
[Regression Potential]
Several patches were required in order to cleanly cherry pick the requested patches. A large number of changes increases the regression potential, however, these pre-requisite patches have been in mainline since early 2018 and the blast radius is localized only to ceph.
