Preallocated file size...

[Luis Claudio R. Goncalves]

Hi!

    Following this message there's a little patch that "corrects" a weird
behavior (or feature) of reply.c - at least in Linux and Solaris boxes.
    If you're writing a file in the disk and you reach the quota roof, the
file will be truncated and zero filled 'till its nominal size - it isn't
a Samba problem, it's a filesystem feature. This simple and ugly patch corrects
the truncated file size every time the above scene happens to any user.
    This patch was released last year and it works fine on 1.9.19 and
2.x . I haven't tested it aginst TNG...

					Hope this helps.
