for easier maintenance; the decision to use either
SMB_TRANS2_QUERY_FS_INFORMATION or SMB_COM_QUERY_INFORMATION_DISK
is done inside it, the code for populating struct statvfs with values
is shared
that userland would pick up correct size of unit (it uses lower of
these values as the size of one 'block' for f_blocks et.al.)
fixes PR bin/25319 by Juan RP
exactly the filename we wanted to lookup, so that file names differing
in case are refused right away
resolves the chdir part of PR kern/22835 by Rob Quinn (cd succeeded when
it was supposed to fail)
convert all code to use smb_{rq|t2}_alloc() instead of allocating
structures on stack, make smb_rq_init()/smb_t2_init() static and not
exported outside smb_rq.c
server supports it
for this, need NT CREATE AND X a directory in smbfs_open(), so that
we get the FID handle used for DIRECTORY CHANGE NOTIFY SMB
this could eventually be used to 'watch' even regular files, by
watching its parent directory and lookup/VN_KNOTE() when we get
REMOVED/RENAMED/MODIFIED action
also reorganize the kqueue code somewhat to use simplify locking
and knote detach
