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" * tag 'nfs-for-5.6-1' of git://git.linux-nfs.org/projects/anna/linux-nfs: (93 commits) NFSv4.0: nfs4_do_fsinfo() should not do implicit lease renewals NFSv4: try lease recovery on NFS4ERR_EXPIRED NFS: Fix memory leaks nfs: optimise readdir cache page invalidation NFS: Switch readdir to using iterate_shared() NFS: Use kmemdup_nul() in nfs_readdir_make_qstr() NFS: Directory page cache pages need to be locked when read NFS: Fix memory leaks and corruption in readdir 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 ...
