Pull cifs updates from Steve French: - improvements to mode bit conversion, chmod and chown when using cifsacl mount option - two new mount options for controlling attribute caching - improvements to crediting and reconnect, improved debugging - reconnect fix - add SMB3.1.1 dialect to default dialects for vers=3 * tag '5.12-smb3-part1' of git://git.samba.org/sfrench/cifs-2.6: (27 commits) cifs: update internal version number cifs: use discard iterator to discard unneeded network data more efficiently cifs: introduce helper for finding referral server to improve DFS target resolution cifs: check all path components in resolved dfs target cifs: fix DFS failover cifs: fix nodfs mount option cifs: fix handling of escaped ',' in the password mount argument cifs: Add new parameter "acregmax" for distinct file and directory metadata timeout cifs: convert revalidate of directories to using directory metadata cache timeout cifs: Add new mount parameter "acdirmax" to allow caching directory metadata cifs: If a corrupted DACL is returned by the server, bail out. cifs: minor simplification to smb2_is_network_name_deleted TCON Reconnect during STATUS_NETWORK_NAME_DELETED cifs: cleanup a few le16 vs. le32 uses in cifsacl.c cifs: Change SIDs in ACEs while transferring file ownership. cifs: Retain old ACEs when converting between mode bits and ACL. cifs: Fix cifsacl ACE mask for group and others. cifs: clarify hostname vs ip address in /proc/fs/cifs/DebugData cifs: change confusing field serverName (to ip_addr) cifs: Fix inconsistent IS_ERR and PTR_ERR ...
