[PATCH 1/6] seq_file: rename mangle_path to seq_mangle_path

From: Johannes Berg The symbol mangle_path conflicts with a gcov symbol which can break the build of ARCH=um with gcov, and it's also not very specific and descriptive. Rename mangle_path() to seq_mangle_path(), and also remove the export since it's not needed or used by any modules. Signed-off

[PATCH 0/6] um: fix up CONFIG_GCOV support

CONFIG_GCOV is fairly useful for ARCH=um (e.g. with kunit, though my main use case is a bit different) since it writes coverage data directly out like a normal userspace binary. Theoretically, that is. Unfortunately, it's broken in multiple ways today: 1) it doesn't like, due to 'mangle_path' in

[PATCH 3/6] .gitignore: also ignore gcda files

From: Johannes Berg We already ignore gcno files that are created by the compiler at build time for -ftest-coverage. However, with ARCH=um it's possible to select CONFIG_GCOV which actually has the kernel binary write out gcda files (rather than have them in debugfs like CONFIG_GCOV_KERNEL does),

[PATCH 4/6] um: split up CONFIG_GCOV

From: Johannes Berg It's not always desirable to collect coverage data for the entire kernel, so split off CONFIG_GCOV_BASE. This option only enables linking with coverage options, and compiles a single file (reboot.c) with them as well to force gcov to be linked into the kernel binary. That way,

[PATCH 6/6] um: fix CONFIG_GCOV for modules

From: Johannes Berg At least with current toolchain versions, gcov (as enabled by CONFIG_GCOV) requires init and exit handlers to run. For modules, this wasn't done properly, so use the new support for CONFIG_MODULE_DESTRUCTORS as well as CONFIG_CONSTRUCTORS to have gcov init and exit called appr

[PATCH 2/6] module: add support for CONFIG_MODULE_DESTRUCTORS

From: Johannes Berg At least in ARCH=um with CONFIG_GCOV (which writes all the coverage data directly out from the userspace binary rather than presenting it in debugfs) it's necessary to run all the atexit handlers (dtors/fini_array) so that gcov actually does write out the data. Add a new conf

[PATCH 5/6] um: fix CONFIG_GCOV for built-in code

From: Johannes Berg With contemporary toolchains, CONFIG_GCOV doesn't work because gcov now relies on both init and exit handlers, but those are discarded from the binary. Fix the linker scripts to keep them instead, so that CONFIG_GCOV can work again. Note that this does not make it work in mod
