CVE-2026-74730

NFS: Pin the 'struct nfs_server' during a FREE_STATEID call

In the Linux kernel, the following vulnerability has been resolved:

NFS: Pin the 'struct nfsserver' during a FREESTATEID call

Dan Aloni reports that he was able to hit a use-after-free bug if a

FREE_STATEID operation gets delayed for whatever reason. Fix this by

bumping the refcount of the 'struct nfs_server' object for the duration

of the FREE_STATEID so it doesn't get cleaned up from underneath us

while operations are still in flight.
