Stable bugfixes:
- Fix memory leaks and corruption in readdir # v2.6.37+
- Directory page cache needs to be locked when read # v2.6.37+
New features:
- Convert NFS to use the new mount API
- Add "softreval" mount option to let clients use cache if server goes down
- Add a config option to compile without UDP support
- Limit the number of inactive delegations the client can cache at once
- Improved readdir concurrency using iterate_shared()
Other bugfixes and cleanups:
- More 64-bit time conversions
- Add additional diagnostic tracepoints
- Check for holes in swapfiles, and add dependency on CONFIG_SWAP
- Various xprtrdma cleanups to prepare for 5.7's changes
- Several fixes for NFS writeback and commit handling
- Fix acls over krb5i/krb5p mounts
- Recover from premature loss of openstateids
- Fix NFS v3 chacl and chmod bug
- Compare creds using cred_fscmp()
- Use kmemdup_nul() in more places
- Optimize readdir cache page invalidation
- Lease renewal and recovery fixes
