What exact trees is this fix for? > > Everything older than 6.13 needs this fix. The code changed between 6.12 and 6.13 which required a backport of the patch for 6.12 and older kernels. All kernels older than 6.13 need this fix. The original backported patch targeted 6.11 and newer stable kernels. 6.11 is EOL so probably just 6.12 unless someone pulled the patch back to some older kernel as well. The commit has been backported to the following kernels: 5.15.174 6.1.120 6.6.66 6.12.5 so can you also send proper fixes for 5.15.y, 6.1.y and 6.6.y as well? thanks, greg k-h
