created a repository for the study regarding linux ram indicators the amounts of tests done for [https://bugzilla.ipr.univ-rennes.fr/show_bug.cgi?id=3897] were becoming messy, so I decided to create a versionned repository for hosting a study on linux ram indicators (because it's actually not trivial, and has been a grey area (not completely clear) for too long for me). So the aim of this repository is to host an article explaining linux ram indicators that can help diagnose ram issues, along with the experimentations and tools that were used to as material for this study: - [measurements] the measurements (results of experiments and tests) - [src] the source code of the tools that - [reference] reference documents note: the file hierarchy is still a bit messy, but much better than the the directory it comes from (~/work/tickets/bug3897) work related to [https://bugzilla.ipr.univ-rennes.fr/show_bug.cgi?id=3897]
