fs: remove call_fsync helper function (2017-07-05 18:44:23 -0400)

----------------------------------------------------------------
The main rationale for all of these changes is to tighten up writeback error reporting to userland. There are many ways now that writeback errors can be lost, such that fsync/fdatasync/msync return 0 when writeback actually failed.

This pile contains a small set of cleanups and writeback error handling fixes that I was able to break off from the main pile (#2).

Two of the patches in this pile are trivial. The exceptions are the patch to fix up error handling in write_one_page, and the patch to make JFS pay attention to write_one_page errors.

Side note: I'm not going to send a PR for the remaining locking patches. Al picked up most of the file locking / fcntl patches from my series in one of his PRs, so all that's left is the l_pid rework from Ben. I think it's reasonable to give those a full cycle to soak in -next as they came in rather late in this cycle anyway.

Obviously, this should have had [GIT PULL] in the subject...
