Reintroduce IO accounting on zvols on Linux 3.19+ zfsonlinux/zfs@e20cd6f7a8922709b1aa2ecefd783390102d79e0 caused us to lose IO accounting on zvols. When I originally wrote that last year, the symbols we needed to maintain IO accounting were GPL exported, but torvalds/linux@394ffa503bc40e32d7f54a9b817264e81ce131b4 provided suitable symbols for restoring this functionality 4 months later. We can call them to restore the IO accounting on Linux 3.19 and later as well as any older kernels where that patch is backported.

Perform KABI checks in parallel Reduce the time required for ./configure to perform the needed KABI checks by allowing kbuild to compile multiple test cases in parallel. This was accomplished by splitting each test's source code from the logic handling whether that code could be compiled or not. By introducing this split it's possible to minimize the number of times kbuild needs to be invoked. As importantly, it means all of the tests can be built in parallel. This does require a little extra care since we expect some tests to fail, so the --keep-going (-k) option must be provided otherwise some tests may not get compiled. Furthermore, since a failure during the kbuild modpost phase will result in an early exit; the final linking phase is limited to tests which passed the initial compilation and produced an object file. Once everything has been built the configure script proceeds as previously. The only significant difference is that it now merely needs to test for the existence of a .ko file to determine the result of a given test. This vastly speeds up the entire process. New test cases should use ZFS_LINUX_TEST_SRC to declare their test source code and ZFS_LINUX_TEST_RESULT to check the result. All of the existing kernel-*.m4 files have been updated accordingly, see config/kernel-current-time.m4 for a basic example.

Linux 5.11 compat: bio_start_io_acct() / bio_end_io_acct() The generic IO accounting functions have been removed in favor of the bio_start_io_acct() and bio_end_io_acct() functions which provide a better interface. These new functions were introduced in the 5.8 kernels but it wasn't until the 5.11 kernel that the previous generic IO accounting interfaces were removed. This commit updates the blk_generic_*_io_acct() wrappers to provide and interface similar to the updated kernel interface. It's slightly different because for older kernels we need to pass the request queue as well as the bio.

When I originally wrote that last year, the symbols we needed to maintain IO accounting were GPL exported, but torvalds/linux@394ffa503bc40e32d7f54a9b817264e81ce131b4 provided suitable symbols for restoring this functionality 4 months later. We can call them to restore the IO accounting on Linux 3.19 and later as well as any older kernels where that patch is backported.
