[PATCH 4/6] btrfs: wake up async_delalloc_pages waiters after submit

by Josef Bacik

We use the async_delalloc_pages mechanism to make sure that we've completed our async work before trying to continue our delalloc flushing. The reason for this is we need to see any ordered extents that were created by our delalloc flushing. However we're waking up before we do the submit work, which is before we create the ordered extents. This is a pretty wide race window where we could potentially think there are no ordered extents and thus exit shrink_delalloc prematurely. Fix this by waking us up after we've done the work to create ordered extents. cc: stable(a)vger.kernel.org Signed-off-by: Josef Bacik <josef(a)toxicpanda.com> --- fs/btrfs/inode.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c index b1f02e3fea5d..e388153c4ae4 100644 --- a/fs/btrfs/inode.c +++ b/fs/btrfs/inode.c @@ -1290,11 +1290,6 @@ static noinline void async_cow_submit(struct btrfs_work *work) nr_pages = (async_chunk->end - async_chunk->start + PAGE_SIZE) >> PAGE_SHIFT; - /* atomic_sub_return implies a barrier */ - if (atomic_sub_return(nr_pages, &fs_info->async_delalloc_pages) < - 5 * SZ_1M) - cond_wake_up_nomb(&fs_info->async_submit_wait); - /* * ->inode could be NULL if async_chunk_start has failed to compress, * in which case we don't have anything to submit, yet we need to @@ -1303,6 +1298,11 @@ static noinline void async_cow_submit(struct btrfs_work *work) */ if (async_chunk->inode) submit_compressed_extents(async_chunk); + + /* atomic_sub_return implies a barrier */ + if (atomic_sub_return(nr_pages, &fs_info->async_delalloc_pages) < + 5 * SZ_1M) + cond_wake_up_nomb(&fs_info->async_submit_wait); } static noinline void async_cow_free(struct btrfs_work *work) -- 2.26.3

[PATCH 2/6] btrfs: handle shrink_delalloc pages calculation differently

by Josef Bacik

We have been hitting some early ENOSPC issues in production with more recent kernels, and I tracked it down to us simply not flushing delalloc as aggressively as we should be. With tracing I was seeing us failing all tickets with all of the block rsvs at or around 0, with very little pinned space, but still around 120MiB of outstanding bytes_may_used. Upon further investigation I saw that we were flushing around 14 pages per shrink call for delalloc, despite having around 2GiB of delalloc outstanding. Consider the example of a 8 way machine, all CPUs trying to create a file in parallel, which at the time of this commit requires 5 items to do. Assuming a 16k leaf size, we have 10MiB of total metadata reclaim size waiting on reservations. Now assume we have 128MiB of delalloc outstanding. With our current math we would set items to 20, and then set to_reclaim to 20 * 256k, or 5MiB. Assuming that we went through this loop all 3 times, for both FLUSH_DELALLOC and FLUSH_DELALLOC_WAIT, and then did the full loop twice, we'd only flush 60MiB of the 128MiB delalloc space. This could leave a fair bit of delalloc reservations still hanging around by the time we go to ENOSPC out all the remaining tickets. Fix this two ways. First, change the calculations to be a fraction of the total delalloc bytes on the system. Prior to this change we were calculating based on dirty inodes so our math made more sense, now it's just completely unrelated to what we're actually doing. Second add a FLUSH_DELALLOC_FULL state, that we hold off until we've gone through the flush states at least once. This will empty the system of all delalloc so we're sure to be truly out of space when we start failing tickets. I'm tagging stable 5.10 and forward, because this is where we started using the page stuff heavily again. This affects earlier kernel versions as well, but would be a pain to backport to them as the flushing mechanisms aren't the same.

[RFC PATCH] ceph: reduce contention in ceph_check_delayed_caps()

by Luis Henriques

Function ceph_check_delayed_caps() is called from the mdsc->delayed_work workqueue and it can be kept looping for quite some time if caps keep being added back to the mdsc->cap_delay_list. This may result in the watchdog tainting the kernel with the softlockup flag. This patch re-arranges the loop through the caps list so that it initially removes all the caps from list, adding them to a temporary list. And then, with less locking contention, it will eventually call the ceph_check_caps() for each inode. Any caps added to the list in the meantime will be handled in the next run. Cc: stable(a)vger.kernel.org Signed-off-by: Luis Henriques <lhenriques(a)suse.de> --- Hi Jeff! So, I've not based this patch on top of your patchset that gets rid of ceph_async_iput() so that it will make it easier to backport it for stable kernels. Of course I'm not 100% this classifies as stable material. Other than that, I've been testing this patch and I couldn't see anything breaking. Let me know what you think. (I *think* I've seen a tracker bug for this in the past but I couldn't find it. I guess it could be added as a 'Link:' tag.)

Patch is now part of Linux 5.13 as commit 1cebcf9932ab ("ARM: dts: stm32: Rework LAN8710Ai PHY reset on DHCOM SoM") It would be nice to pick it into stable, since it fixes ethernet stability issues on the device.

FAILED: patch "[PATCH] mm/hwpoison: do not lock page again when me_huge_page()" failed to apply to 5.10-stable tree

The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From ea6d0630100b285f059d0a8d8e86f38a46407536 Mon Sep 17 00:00:00 2001 From: Naoya Horiguchi <naoya.horiguchi(a)nec.com> Date: Thu, 24 Jun 2021 18:40:01 -0700 Subject: [PATCH] mm/hwpoison: do not lock page again when me_huge_page() successfully recovers Currently me_huge_page() temporary unlocks page to perform some actions then locks it again later. My testcase (which calls hard-offline on some tail page in a hugetlb, then accesses the address of the hugetlb range) showed that page allocation code detects this page lock on buddy page and printed out "BUG: Bad page state" message. check_new_page_bad() does not consider a page with __PG_HWPOISON as bad page, so this flag works as kind of filter, but this filtering doesn't work in this case because the "bad page" is not the actual hwpoisoned page. So stop locking page again. Actions to be taken depend on the page type of the error, so page unlocking should be done in ->action() callbacks. So let's make it assumed and change all existing callbacks that way.
