Merge tag '6.4-rc-smb3-client-fixes-part1' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs fixes from Steve French: - deferred close fix for an important case when cached file should be closed immediately - two fixes for missing locks - eight minor cleanup * tag '6.4-rc-smb3-client-fixes-part1' of git://git.samba.org/sfrench/cifs-2.6: cifs: update internal module version number for cifs.ko smb3: move some common open context structs to smbfs_common smb3: make query_on_disk_id open context consistent and move to common code SMB3.1.1: add new tree connect ShareFlags cifs: missing lock when updating session status SMB3: Close deferred file handles in case of handle lease break SMB3: Add missing locks to protect deferred close file list cifs: Avoid a cast in add_lease_context() cifs: Simplify SMB2_open_init() cifs: Simplify SMB2_open_init() cifs: Simplify SMB2_open_init()
