| | | | | | | | | | Use group allocation/free of per-cpu counters api to accelerate blkg_rwstat_init/exit() and simplify code.

* | blk-cgroup: Fix the recursive blkg rwstat | Xunlei Pang | 2021-03-05 | 1 | -1/+2 |
| | | | | | | | | | | | | | | | | | | | | | | | | | The current blkio.throttle.io_service_bytes_recursive doesn't work correctly. As an example, for the following blkcg hierarchy: (Made 1GB READ in test1, 512MB READ in test2) test / \ test1 test2 $ head -n 1 test/test1/blkio.throttle.io_service_bytes_recursive 8:0 Read 1073684480 $ head -n 1 test/test2/blkio.throttle.io_service_bytes_recursive 8:0 Read 537448448 $ head -n 1 test/blkio.throttle.io_service_bytes_recursive 8:0 Read 537448448 Clearly, above data of "test" reflects "test2" not "test1"+"test2". Do the correct summary in blkg_rwstat_recursive_sum(). Signed-off-by: Xunlei Pang <xlpang@linux.alibaba.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> | ||||
* | blk-cgroup: separate out blkg_rwstat under CONFIG_BLK_CGROUP_RWSTAT | Tejun Heo | 2019-11-07 | 1 | -0/+129 |
blkg_rwstat is now only used by bfq-iosched and blk-throtl when on cgroup1. Let's move it into its own files and gate it behind a config option. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
