Subject: fuse: implement i_op->atomic_open() prevents writes to ntfs-3g filesystem

[repost, apologies if you see it twice]
I'm running Debian unstable on AMD64 (quad core) with Linus' github.com 
kernels.

Recently (post 3.5.0 kernels) writes to an ntfs-3g filesystem started 
failing, and I bisected back to the following:

# git bisect good
c8ccbe032feb127a977c66865cb63d72d9a6e08b is the first bad commit
commit c8ccbe032feb127a977c66865cb63d72d9a6e08b

     fuse: implement i_op->atomic_open()

     Add an ->atomic_open implementation which replaces the atomic 
open+create
     operation implemented via ->create.  No functionality is changed.

Has this problem been seen by anyone else?

Is a fix already in the works?

Regards,

Arthur.
