From: Kent Overstreet To: torvalds@linux-foundation.org Cc: linux-kernel@vger.kernel.org, linux-fsdevel@vger.kernel.org, linux-bcachefs@vger.kernel.org Subject: [GIT PULL] bcachefs Message-ID: <20230626214656.hcp4puionmtoloat@moria.home.lan> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-Migadu-Flow: FLOW_OUT Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi Linus, Here it is, the bcachefs pull request. For brevity the list of patches below is only the initial part of the series, the non-bcachefs prep patches and the first bcachefs patch, but the diffstat is for the entire series. Six locks has all the changes you suggested, text size went down significantly. If you'd still like this to see more review from the locking people, I'm not against them living in fs/bcachefs/ as an interim; perhaps Dave could move them back to kernel/locking when he starts using them or when locking people have had time to look at them - I'm just hoping for this to not block the merge. Recently some people have expressed concerns about "not wanting a repeat of ntfs3" - from what I understand the issue there was just severe buggyness, so perhaps showing the bcachefs automated test results will help with that: https://evilpiepirate.org/~testdashboard/ci The main bcachefs branch runs fstests and my own test suite in several varations, including lockdep+kasan, preempt, and gcov (we're at 82% line coverage); I'm not currently seeing any lockdep or kasan splats (or panics/oopses, for that matter). (Worth noting the bug causing the most test failures by a wide margin is actually an io_uring bug that causes random umount failures in shutdown tests. Would be great to get that looked at, it doesn't just affect bcachefs). Regarding feature status - most features are considered stable and ready for use, snapshots and erasure coding are both nearly there. But a filesystem on this scale is a massive project, adequately conveying the status of every feature would take at least a page or two. We may want to mark it as EXPERIMENTAL for a few releases, I haven't done that as yet. (I wouldn't consider single device without snapshots to be experimental, but - given that the number of users and bug reports is about to shoot up, perhaps I should...).
