locking: Rebase locking code to v6.8
JIRA: https://issues.redhat.com/browse/RHEL-35759
MR: !4190 (merged)
Rebase the kernel locking code up to v6.8. There aren't significant locking updates since the 9.4 update. The more significant ones are the seqlock and the locktorture test update. The others are mostly miscellaneous updates and cleanups.
