We did some work on analyzing patches potentially missing from stable releases based on the Fixes: and Revert references in the commit messages. Our script is based on similar idea as described by Guenter Roeck in this earlier mail: https://lore.kernel.org/stable/20190827171621.GA30360@xxxxxxxxxxxx/. Although the list is not comprehensive, we figured it makes sense to publish it in case the results are of interest to someone else also. The below list of potentially missing commits is based on 4.19, but some of the commits might also apply to 5.4 and 5.6. For each potentially missing commit flagged by the script, we read the commit message and had a short look at the change. We then added comments on our own judgement if it might be stable material or not. No comments simply means the potentially missing patch appears stable material. "Based on commit" is the mainline patch that has been backported to 4.19 and is referenced by the missing commit. We did not check if the patch applies without changes, nor did we build or execute any tests. 6011002c1584 uio: make symbol 'uio_class_registered' static Based on commit: ae61cf5b9913 968339fad422 powerpc/boot: Delete unneeded .globl _zimage_start Based on commit: ee9d21b3b358 Comment: not stable material? ed4d81c4b3f2 net: aquantia: when cleaning hw cache it should be toggled Based on commit: 7a1bb49461b1 Comment: this was backported to 5.3, but for some reason not to older stable releases b27507bb59ed net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can ru Based on commit: a5681e20b541 61c347ba5511 afs: Clear AFS_VNODE_CB_PROMISED if we detect callback expiry Based on commit: ae3b7361dc0e Comment: likely requires manual backport 1a49b2fd8f58 kbuild: strip whitespace in cmd_record_mcount findstring Based on commit: 6977f95e63b9 Comment: not stable material? 669e859b5ea7 btrfs: drop the lock on error in btrfs_dev_replace_cancel Based on commit: d189dd70e255 Comment: earlier backport failed, this would likely require manual backport: https://lore.kernel.org/stable/15531096685894@xxxxxxxxx/ dddaf89e2fbc netfilter: ipt_CLUSTERIP: make symbol 'cip_netdev_notifier' stat Based on commit: 5a86d68bcf02 01091c496f92 acpi/nfit: improve bounds checking for 'func' Based on commit: 11189c1089da Comment: the missing commit was picked by AUTOSEL to 5.4, 5.5, and 5.6, but for some reason, it was not backported 4.19: https://lore.kernel.org/stable/?q=01091c496f92* 2b74c878b0ea IB/hfi1: Unreserve a flushed OPFN request Based on commit: ca95f802ef51 Comment: earlier backport failed, this would likely require manual backport: https://lore.kernel.org/stable/15649835016938@xxxxxxxxx/ 0b815023a1d4 bnxt_en: Fix ring checking logic on 57500 chips.
