[Leonardo Taccari]

Patch coming... sorry, that was my first time using Tools/Scripts/webkit-patch and it seems that it didn't well well!

sysinfo(2)/sysinfo(3) is used only on FreeBSD and Linux and could be not available in other Unix-like operating systems.

This commit message doesn't comply with WebKit format. WebKit has own prepare-commit-msg hook.
"./Tools/Scripts/git-webkit setup" will setup for you. Could you redo this patch with it?

Marking it as obsolete because the commit message format is not okay.

(Sorry, I didn't known about `Tools/Scripts/git-webkit setup`, thanks to Fujii for pointing it out, patch hopefully adjusted coming soon!)

Sure! (sorry, I didn't known about it)

I have hopefully reformatted it accordingly. If it needs further adjustment please let me know and/or feel free to adjust the commit message as you prefer.


Thank you!

Unfortunately, sytle checker doesn't like this change.

#if BOS(FREEBSD) || BOS(LINUX)
#include <sys/sysinfo.h>
#endif

This condition matches with the implementation of AvailableMemory.cpp.

You can style errors with Tools/Scripts/check-webkit-style before uploading.
If you use `webkit-patch upload` or `git-webkit pr` scripts to upload your patch, it automatically run check-webkit-style.

If you don't mind, it'd be great if you change another conidtion to `#if OS(LINUX) || OS(FREEBSD)` in this patch to match with the implementation.

I would prefer to do that in a separate patch to avoid possible regressions (I think that the components are separate and this bug actually fix build on non-FreeBSD/non-Linux Unix-like operating systems while the change in RAMSize.cpp will possibly impact FreeBSD only).

Thanks, I have resubmitted it and I hope it's fine this time!
