| |
After two days uptime on my NFS4 server with 2.6.31-rc4 and a few 2.6.28 clients, I hit the file write-count WARN_ON(f->f_mnt_write_state != 0) in file_take_write() in the nfsd4_open path [1].
I can't find this reported elsewhere; let me know if it's preferred in bugzilla.kernel.org etc.
Thanks, Daniel
