This is confusing and there's no way Greg is going to do this right given the limited information you've provided and wrong ordering of the patches. I couldn't really even follow this without some detective work, and I wrote these patches. Here are your options: - Let the revert of "97ef77c52b78 fs: check FMODE_LSEEK to control internal pipe splicing" work its way into all stable trees; or - Send a proper backport series for each and every stable kernel, depending on what each one needs. Send these as different patchsets, marked with the version number it applies to. Make sure they apply, compile, and work correctly. Anything short of those is going to lead to chaos. Jason
