2023-06-10	kmemleak-test: drop __init to get better backtrace	Jim Cromie	1	-1/+1
	Drop the __init on kmemleak_test_init(). With it, the storage is reclaimed, but then the symbol isn't available for "%pS" rendering, and the backtrace gets a bare pointer where the actual leak happened. unreferenced object 0xffff88800a2b0800 (size 1024): comm "modprobe", pid 413, jiffies 4294953430 hex dump (first 32 bytes): 73 02 00 00 75 01 00 68 02 00 00 01 00 00 00 04 s...u..h........ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000fabad728>] kmalloc_trace+0x26/0x90 [<00000000ef738764>] 0xffffffffc02350a2 [<00000000004e5795>] do_one_initcall+0x43/0x210 [<00000000d768905e>] do_init_module+0x4a/0x210 [<0000000087135ab5>] __do_sys_finit_module+0x93/0xf0 [<000000004fcb1fa2>] do_syscall_64+0x34/0x80 [<00000000c73c8d9d>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 with __init gone, that trace entry renders like: [<00000000ef738764>] kmemleak_test_init+<offset>/<size> Link: https://lkml.kernel.org/r/20230525174356.69711-1-jim.cromie@gmail.com Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2020-10-14	mm,kmemleak-test.c: move kmemleak-test.c to samples dir	Hui Su	1	-0/+99
	kmemleak-test.c is just a kmemleak test module, which also can not be used as a built-in kernel module. Thus, i think it may should not be in mm dir, and move the kmemleak-test.c to samples/kmemleak/kmemleak-test.c. Fix the spelling of built-in by the way.
