<html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hello, <div class="moz-forward-container"> There is what appears to me to be a glaring bug in the kbuild-patch script. Immediately after the script builds the original kernel, the following line should appear (but does not): >$TEMPDIR/changed_objs Without that line, the script goes on to die with a bogus "invalid ancestor" error. If you turn those bogus errors into warnings, then the script goes on to incorrectly put into the generated .ko file every single function that was compiled in the *original* kernel build, thereby producing an immense .ko file with more than 64k sections that the linux kernel cannot load. Adding the above line fixes everything. Indeed, the description in README.md of how kpatch-build works implies that the above line has to be present in the kpatch-build script. Fascinatingly enough, I have poked around through the git history and I cannot find the above line present in any earlier commit state. (I also cannot find a mention of this issue in the mail archives, although I might have missed it.) So I am wondering, how in the world does this script work for all of you?
