Suggested patch

Description of problem:
- window-size option does not work when it is > 128KB
- trickling-writes is not configurable

Version-Release number of selected component (if applicable): 3.8

How reproducible: Always

Steps to Reproduce:
1. Write a 1MB file to a gluster mount and observe write sizes on the bricks.

Actual results: Write sizes are always buffered into 'page-size' (128KB) chunks rather than 'window-size' chunks.

Expected results: We expect the window-size to be respected and the writes buffered accordingly.

Comment 3 Niels de Vos 2017-11-07 10:37:11 UTC
This bug is getting closed because the 3.8 version is marked End-Of-Life. There will be no further updates to this version. Please open a new bug against a version that still receives bugfixes if you are still facing this issue in a more current release.
