This hits me, too. Reverting it cures the problem.
(BTW, the correct commit id of the affecting patch is
af7fa16506bf9b6323e862a61e14c20555152bb3
"NFS: Fix up the fsync code")
Reproduced on 2.6.36-rc1.
Looking at strace output,
open("afo", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
write(4, "#!/bin\n", 7) = 7
fsync(4) = 1
stat("afo", {st_mode=S_IFREG|0644, st_size=7, ...}) = 0
close(4) = 0
So, fsync() returns 1 wrongly.
thanks,
Takashi
