Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs fixes from Steve French: "Various fixes for stable for CIFS/SMB3 especially for better interoperability for SMB3 to Macs. It also includes Pavel's improvements to SMB3 async i/o support (which is much faster now)" * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: CIFS: add misssing SFM mapping for doublequote SMB3: Work around mount failure when using SMB3 dialect to Macs cifs: fix CIFS_IOC_GET_MNT_INFO oops CIFS: fix mapping of SFM_SPACE and SFM_PERIOD CIFS: fix oplock break deadlocks cifs: fix CIFS_ENUMERATE_SNAPSHOTS oops cifs: fix leak in FSCTL_ENUM_SNAPS response handling Set unicode flag on cifs echo request to avoid Mac error CIFS: Add asynchronous write support through kernel AIO CIFS: Add asynchronous read support through kernel AIO CIFS: Add asynchronous context to support kernel AIO cifs: fix IPv6 link local, with scope id, address parsing cifs: small underflow in cnvrtDosUnixTm()
