That was a fix for a regression introduced in 6.3-rc1, and hence does not exist in 6.1.y kernels. The problem you are tripping over appears to be a livelock in the page cache iterator infrastructure, not an issue with the filesystem itself. This has been seen occasionally (maybe once every couple of months of testing across the entire dev community) during testing since large folios were enabled in the page cache, but nobody has been able to reproduce it reliably enough to be able to isolate the root cause and fix it yet. If you can reproduce it reliably and quickly, then putting together a recipe that we can use to trigger it would be a great help. -Dave. -- Dave Chinner david@xxxxxxxxxxxxx
