Merge tag 'nfs-for-5.6-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Puyll NFS client updates from Anna Schumaker:
"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"

SUNRPC: Use kmemdup_nul() in rpc_parse_scope_id()
NFS: Replace various occurrences of kstrndup() with kmemdup_nul()
NFSv4: Limit the total number of cached delegations
NFSv4: Add accounting for the number of active delegations held
NFSv4: Try to return the delegation immediately when marked for return on close
NFS: Clear NFS_DELEGATION_RETURN_IF_CLOSED when the delegation is returned
NFSv4: nfs_inode_evict_delegation() should set NFS_DELEGATION_RETURNING
NFS: nfs_find_open_context() should use cred_fscmp()
NFS: nfs_access_get_cached_rcu() should use cred_fscmp()
NFSv4: pnfs_roc() must use cred_fscmp() to compare creds
NFS: remove unused macros
nfs: Return EINVAL rather than ERANGE for mount parse errors
