GrapheneOS f2fs Data Corruption Fixes News (grapheneos.social)

GrapheneOS ships kernel updates much faster than stock Pixel OS. For devices using 5.10 LTS branch, we're on latest 5.10.199 revision compared to the stock OS being on 5.10.157. This can be a hassle due to regressions we need to solve, but it recently saved us a lot of trouble.

Android 14 released with a major f2fs data corruption bug caused by LTS kernel backporting shenanigans. This was already resolved in the kernel shipped by GrapheneOS in our experimental Android 14 release on October 6th/7th (we ported in around 2 days after it was published).

In addition to fixing a backport, November release of AOSP and stock Pixel OS include a few robustness improvements to hold up better against future f2fs data corruption bugs or hardware issues causing data corruption. f2fs recently incorporated those improvements upstream too.
