Bug #5837: IO#fsync documentation typo quickfix
https://bugs.ruby-lang.org/issues/5837

Author: Kyle Drake
Status: Open
Priority: Normal
Assignee: Eric Hodel
Category: DOC
Target version: 
ruby -v: 1.9.3


The documentation IO#fsync says:

"Immediately writes all buffered data in ios to disk. Note that fsync differs from using IO#sync=. The latter ensures that data is flushed from Ruby���s buffers, but doesn���t not guarantee that the underlying operating system actually writes it to disk."

I believe the "doesn't not" should be changed to "does not". Fsync(2) traditionally guarantees that the operating system writes to disk, so I'm assuming that IO#sync does not and that IO#fsync does.

There is probably a better description that could be written here, but this clears up the typo for the interim.
