Subject: [GIT PULL] NFSD changes for v6.8
Hello Linus -

nfsd: rename nfsd_last_thread() to nfsd_destroy_serv() (2024-01-07 17:54:33 -0500)
----------------------------------------------------------------
NFSD 6.8 Release Notes
The bulk of the patches for this release are clean-ups and minor bug
fixes.
There is one significant revert to mention: support for RDMA Read
operations in the server's RPC-over-RDMA transport implementation
has been fixed so it waits for Read completion in a way that avoids
tying up an nfsd thread. This prevents a possible DoS vector if an
RPC-over-RDMA client should become unresponsive during RDMA Read
operations.
As always I am grateful to NFSD contributors, reviewers, and
testers.
