* Linux 5.12 compat: replace bio_*_io_acct with disk_*_io_acctColeman Kane2021-02-241-22/+47
| | | | | | | | | | | | The bio_*_acct functions became GPL exports, which causes the kernel modules to refuse to compile. This replaces code with alternate function calls to the disk_*_io_acct interfaces, which are not GPL exports. This change was added in kernel commit 99dfc43ecbf67f12a06512918aaba61d55863efc.

* Linux 5.11 compat: bio_start_io_acct() / bio_end_io_acct()Brian Behlendorf2020-12-271-12/+35
| | | | | | | | | | | | | | | | | | | 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.

* Perform KABI checks in parallelBrian Behlendorf2019-10-011-26/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. The legacy ZFS_LINUX_TRY_COMPILE macro has been kept to handle special cases but it's use is not encouraged. master (secs) patched (secs) ------------- ---------------- autogen.sh 61 68 configure 137 24 (~17% of current run time) make -j $(nproc) 44 44 make rpms 287 150 Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #8547 Closes #9132 Closes #9341
* Linux 3.14 compat: IO acct, global_page_state, etcGiuseppe Di Natale2017-09-161-4/+31
| | | | | | | | | | | | | | | | | | | | | | generic_start_io_acct/generic_end_io_acct in the master branch of the linux kernel requires that the request_queue be provided. Move the logic from freemem in the spl to arc_free_memory in arc.c. Do this so we can take advantage of global_page_state interface checks in zfs. Upstream kernel replaced struct block_device with struct gendisk in struct bio. Determine if the function bio_set_dev exists during configure and have zfs use that if it exists. bio_set_dev https://github.com/torvalds/linux/commit/74d4699 global_node_page_state https://github.com/torvalds/linux/commit/75ef718 io acct https://github.com/torvalds/linux/commit/d62e26b Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Giuseppe Di Natale <[email protected]> Closes #6635
* Reintroduce IO accounting on zvols on Linux 3.19+Richard Yao2015-09-091-0/+26
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.
