Re: [PATCH] fuse: allow umask processing in userspace

[Jean-Pierre ANDRE <jean-pierre.andre-39ZsbGIQGT5GWvitb5QawA@public.gmane.org>]

Hi Miklos,

Great, I appreciate.

I cannot test it now, I will from July.

I will probably have questions when I start testing, just one
for now : what condition should be checked in the source of a file
system for being compiled with the new interface (probably a
minimal value for fuse version) ? Obviously the file system
will have to be released will ability to be compiled in both
situations.

Thank you again,

Jean-Pierre
