And\nthe damon_region which is allocated in damon_new_region() in\ndamon_set_regions() is also not freed.\n\nSo use damon_destroy_target to free all the damon_regions and damon_target.\n\n unreferenced object 0xffff888107c9a940 (size 64):\n comm \"kunit_try_catch\", pid 1069, jiffies 4294670592 (age 732.761s)\n hex dump (first 32 bytes):\n 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b ............kkkk\n 60 c7 9c 07 81 88 ff ff f8 cb 9c 07 81 88 ff ff `...............\n backtrace:\n [<ffffffff817e0167>] kmalloc_trace+0x27/0xa0\n [<ffffffff819c11cf>] damon_new_target+0x3f/0x1b0\n [<ffffffff819c7d55>] damon_do_test_apply_three_regions.constprop.0+0x95/0x3e0\n [<ffffffff819c82be>] damon_test_apply_three_regions1+0x21e/0x260\n [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90\n [<ffffffff81237cf6>] kthread+0x2b6/0x380\n [<ffffffff81097add>] ret_from_fork+0x2d/0x70\n [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20\n unreferenced object 0xffff8881079cc740 (size 56):\n comm \"kunit_try_catch\", pid 1069, jiffies 4294670592 (age 732.761s)\n hex dump (first 32 bytes):\n 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................\n 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk\n backtrace:\n [<ffffffff819bc492>] damon_new_region+0x22/0x1c0\n [<ffffffff819c7d91>] damon_do_test_apply_three_regions.constprop.0+0xd1/0x3e0\n [<ffffffff819c82be>] damon_test_apply_three_regions1+0x21e/0x260\n [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90\n [<ffffffff81237cf6>] kthread+0x2b6/0x380\n [<ffffffff81097add>] ret_from_fork+0x2d/0x70\n [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20\n unreferenced object 0xffff888107c9ac40 (size 64):\n comm \"kunit_try_catch\", pid 1071, jiffies 4294670595 (age 732.843s)\n hex dump (first 32 bytes):\n 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b ............kkkk\n a0 cc 9c 07 81 88 ff ff 78 a1 76 07 81 88 ff ff ........x.v.....\n backtrace:\n [<ffffffff817e0167>] kmalloc_trace+0x27/0xa0\n [<ffffffff819c11cf>] damon_new_target+0x3f/0x1b0\n [<ffffffff819c7d55>] damon_do_test_apply_three_regions.constprop.0+0x95/0x3e0\n [<ffffffff819c851e>] damon_test_apply_three_regions2+0x21e/0x260\n [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90\n [<ffffffff81237cf6>] kthread+0x2b6/0x380\n [<ffffffff81097add>] ret_from_fork+0x2d/0x70\n [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20\n unreferenced object 0xffff8881079ccc80 (size 56):\n comm \"kunit_try_catch\", pid 1071, jiffies 4294670595 (age 732.843s)\n hex dump (first 32 bytes):\n 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................\n 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk\n backtrace:\n [<ffffffff819bc492>] damon_new_region+0x22/0x1c0\n [<ffffffff819c7d91>] damon_do_test_apply_three_regions.constprop.0+0xd1/0x3e0\n [<ffffffff819c851e>] damon_test_apply_three_regions2+0x21e/0x260\n [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90\n [<ffffffff81237cf6>] kthread+0x2b6/0x380\n [<ffffffff81097add>] ret_from_fork+0x2d/0x70\n [<ffff\n---truncated---" |
