Subject: [PATCH 1/2] fuse: fix uninitialized field in fuse_inode

Andrew,

Please queue these two fixes for 2.6.24, along with the rest of the
fuse patches currently in -mm.

Thanks,
Miklos

I found problems accessing (executing) previously existing files, until
I did chmod on them (or setattr).

If the fi->attr_version is not initialized, then it could be
larger than fc->attr_version until a setattr is executed, and as a
result the inode attributes would never be set.
