Linus Torvalds 04de788e61 NFS client updates for Linux 5.7
Highlights include:
 
 Stable fixes:
 - Fix a page leak in nfs_destroy_unlinked_subrequests()
 - Fix use-after-free issues in nfs_pageio_add_request()
 - Fix new mount code constant_table array definitions
 - finish_automount() requires us to hold 2 refs to the mount record
 
 Features:
 - Improve the accuracy of telldir/seekdir by using 64-bit cookies when
   possible.
 - Allow one RDMA active connection and several zombie connections to
   prevent blocking if the remote server is unresponsive.
 - Limit the size of the NFS access cache by default
 - Reduce the number of references to credentials that are taken by NFS
 - pNFS files and flexfiles drivers now support per-layout segment
   COMMIT lists.
 - Enable partial-file layout segments in the pNFS/flexfiles driver.
 - Add support for CB_RECALL_ANY to the pNFS flexfiles layout type
 - pNFS/flexfiles Report NFS4ERR_DELAY and NFS4ERR_GRACE errors from
   the DS using the layouterror mechanism.
 
 Bugfixes and cleanups:
 - SUNRPC: Fix krb5p regressions
 - Don't specify NFS version in "UDP not supported" error
 - nfsroot: set tcp as the default transport protocol
 - pnfs: Return valid stateids in nfs_layout_find_inode_by_stateid()
 - alloc_nfs_open_context() must use the file cred when available
 - Fix locking when dereferencing the delegation cred
 - Fix memory leaks in O_DIRECT when nfs_get_lock_context() fails
 - Various clean ups of the NFS O_DIRECT commit code
 - Clean up RDMA connect/disconnect
 - Replace zero-length arrays with C99-style flexible arrays
