To: Suresh Jayaraman; +Cc: linux-cifs
At the moment ls won't work if there are more than one buffer file of files.
I made various fixes to the readdir code three weeks ago. There were
problems in the code which handles file close (it now has to handle
directory close as well) and file initialization (which now has to
handle directory open, not just file open). The other fixes handled
an "off by one" error in the parsing of the first readdir response.
The search continuation code is not implemented and that might be what
you are hitting.
Will look at that this afternoon, but cifs patch reviewing/merging
(especially Jeff's 30+ patches and also Shirish's patches) has been
occupying a lot of time. Thank you for reviewing Jeff's patch series
- it makes it easier/quicker.
