I noticed that we don't have these six flags defined in cifsglob.h in the CIFS_MOUNT_MASK used to see if superblocks match when doing a second mount of the same share #define CIFS_MOUNT_RWPIDFORWARD 0x80000 #define CIFS_MOUNT_POSIXACL 0x100000 #define CIFS_MOUNT_USE_PREFIX_PATH 0x1000000 #define CIFS_MOUNT_UID_FROM_ACL 0x2000000 #define CIFS_MOUNT_NO_HANDLE_CACHE 0x4000000 #define CIFS_MOUNT_MAP_SFM_CHR 0x800000 Any thoughts if any of thes really can be ignored in the check for superblock matches? -- Thanks, Steve
