CVS commit: src/lib/libperfuse

["Emmanuel Dreyfus" <manu%netbsd.org@localhost>]

Module Name:    src
Committed By:   manu

Modified Files:
        src/lib/libperfuse: ops.c

Log Message:
Fix race conditions between write and getattr/setattr, which lead to
inconsitencies between kernel and filesystem idea of file size during
writes with IO_APPEND.

At mine, this resulted in a configure script producing config.status
with ": clr\n" lines stripped (not 100% reproductible, but always this
specific string. That is of little interest except for my own future
reference).

When a write is in progress, getattr/setattr get/set the maximum size
among kernel idea (grown by write) and filesystem idea (not yet grown).
