From 2d76e79315e403aab595d4c8830b7a46c19f0f3b Mon Sep 17 00:00:00 2001 From: "Uladzislau Rezki (Sony)" Date: Thu, 17 Apr 2025 18:12:14 +0200 Subject: lib/test_vmalloc.c: allow built-in execution Remove the dependency on module loading ("m") for the vmalloc test suite, enabling it to be built directly into the kernel, so both ("=m") and ("=y") are supported. Motivation: - Faster debugging/testing of vmalloc code; - It allows to configure the test via kernel-boot parameters. Configuration example: test_vmalloc.nr_threads=64 test_vmalloc.run_test_mask=7 test_vmalloc.sequential_test_order=1 Link: https://lkml.kernel.org/r/20250417161216.88318-2-urezki@gmail.com Signed-off-by: Uladzislau Rezki (Sony) Reviewed-by: Baoquan He Reviewed-by: Adrian Huang Tested-by: Adrian Huang Cc: Christop Hellwig Cc: Mateusz Guzik Signed-off-by: Andrew Morton --- lib/test_vmalloc.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'lib/test_vmalloc.c') diff --git a/lib/test_vmalloc.c b/lib/test_vmalloc.c index 399751022eea..1b0b59549aaf 100644 --- a/lib/test_vmalloc.c +++ b/lib/test_vmalloc.c @@ -591,10 +591,11 @@ static void do_concurrent_test(void) kvfree(tdriver); } -static int vmalloc_test_init(void) +static int __init vmalloc_test_init(void) { do_concurrent_test(); - return -EAGAIN; /* Fail will directly unload the module */ + /* Fail will directly unload the module */ + return IS_BUILTIN(CONFIG_TEST_VMALLOC) ? 0:-EAGAIN; } module_init(vmalloc_test_init) -- cgit v1.2.3
