 Hi, everybody:
       I read the function smbd_do_qfsinfo.  I found that in case SMB_INFO_ALLOCATION, there is following  sentence:
      My question is why use  st.st_ex_dev ?  Actually, according to [MS-CIFS], it is the id of file system. If we call the function statfs, we will get the  struct statfs *buf.  In this struct, there is a "fsid_t f_fsid;". Why not use this  f_fsid?
