Hi openEler kernel maintainer, This is the bcache backport since Linux v4.19 to v5.5 for openEuler-10 kernel. All the patches are based on openEuler-1.0 commit cf975ca6a64a ("Document: add guideline to submitting patches to openEuler"). This patch set survives for 2+ hours smoking test on a 48x2 cores Taishan machine. Pleasse review and consider to pick them. Thanks in advance.

Proposed to imporve your repos/projects readability
by Liyongle (Fred) 06 Jan '20

06 Jan '20

Hi all, At this early stage, many developers are coming to see the projects. To make visitors easier to understand the project, it is proposed to improve the following: - README It is better to provide both English[1] and Chinese[2]. - Meeting schedule Please provide meeting schedule and add the information to your readme. The example is [3]. - Contact Mail and IRC. - Team members Please be sure to including Maintainers, committers and contributors. This is a way to respect every contributor, and let new contributors to understand who to talk. - How to contribute Different projects have their own way to contribute. Some projects (like community) are mainly documents, some are codes and some are buildings. Please provide the contribution guidance for your own projects. - Other useful information Your advice and good practice are valuable.
