[PATCH STABLE 4.14] Revert "Input: synaptics-rmi4 - avoid processing unknown IRQs"

by Evan Green

This reverts commit 7b9f7a928255a232012be55cb95db30e963b83a7. That change should have had a fixes tag for commit 24d28e4f1271 ("Input: synaptics-rmi4 - convert irq distribution to irq_domain"). The conversion to irq_domain introduced the issue being fixed by this commit. In older kernels the bitmap IRQ accounting is done differently, and it doesn't suffer from the same issue of calling handle_nested_irq(0). Keeping this commit on kernels 4.14 and older causes problems with touchpads due to the different semantics of the IRQ bitmasks. Signed-off-by: Evan Green <evgreen(a)chromium.org> --- This revert is only needed on 4.14 where the driver is not yet converted to irq_domain and the existing bitmasks work fine.

[PATCH] gfs2: fix glock reference problem in gfs2_trans_remove_revoke

by Andreas Gruenbacher

From: Bob Peterson <rpeterso(a)redhat.com> Commit 9287c6452d2b fixed a situation in which gfs2 could use a glock after it had been freed. To do that, it temporarily added a new glock reference by calling gfs2_glock_hold in function gfs2_add_revoke. However, if the bd element was removed by gfs2_trans_remove_revoke, it failed to drop the additional reference. This patch adds logic to gfs2_trans_remove_revoke to properly drop the additional glock reference.

[PATCH][V2] ovl: fix lookup failure on multi lower squashfs

by Colin King

From: Colin Ian King <colin.king(a)canonical.com> In the past, overlayfs required that lower fs have non null uuid in order to support nfs export and decode copy up origin file handles. Commit 9df085f3c9a2 ("ovl: relax requirement for non null uuid of lower fs") relaxed this requirement for nfs export support, as long as uuid (even if null) is unique among all lower fs. However, said commit unintentionally also relaxed the non null uuid requirement for decoding copy up origin file handles, regardless of the unique uuid requirement. Amend this mistake by disabling decoding of copy up origin file handle from lower fs with a conflicting uuid. We still encode copy up origin file handles from those fs, because file handles like those already exist in the wild and because they might provide useful information in the future.

[PATCH 1/3] rtlwifi: rtl8192de: Fix missing code to retrieve RX buffer address

In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for new drivers"), a callback to get the RX buffer address was added to the PCI driver.

✅ PASS: Stable queue: queue-5.3

by CKI Project

Hello, We ran automated tests on a patchset that was proposed for merging into this kernel tree. The patches were applied to: Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git Commit: 116a395b7061 - Linux 5.3.11 The results of these automated tests are provided below. Overall result: PASSED Merge: OK Compile: OK Tests: OK All kernel binaries, config files, and logs are available for download here: https://artifacts.cki-project.org/pipelines/284540 Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running are marked with ⏱. Reports for non-upstream kernels have a Beaker recipe linked to next to each host.
