>From 1ecab5281e3cfc8c2a61648410c8b25ba2654fcb Mon Sep 17 00:00:00 2001 From: George Spelvin <li...@horizon.com> Date: Thu, 29 May 2014 00:08:03 -0400 Subject: [PATCH 2/3] lib: crc32: mark test data __initconst
So it gets discarded after the selftest. Signed-off-by: George Spelvin <li...@horizon.com> --- This is the patch I started with, when I was looking for lib/ self-test code to emulate for my still-pending glob.c code. But curiosity about the combine code led me notice problems with it, and to study the arch/x86/crypto code, where I also have a proposed patch. Aren't tangents fun? lib/crc32.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/crc32.c b/lib/crc32.c index a4a576f3..977167d6 100644 --- a/lib/crc32.c +++ b/lib/crc32.c @@ -341,7 +341,7 @@ EXPORT_SYMBOL(crc32_be); #ifdef CONFIG_CRC32_SELFTEST /* 4096 random bytes */ -static u8 __attribute__((__aligned__(8))) test_buf[] = +static u8 const __aligned(8) test_buf[] __initconst = { 0x5b, 0x85, 0x21, 0xcb, 0x09, 0x68, 0x7d, 0x30, 0xc7, 0x69, 0xd7, 0x30, 0x92, 0xde, 0x59, 0xe4, @@ -865,7 +865,7 @@ static struct crc_test { u32 crc_le; /* expected crc32_le result */ u32 crc_be; /* expected crc32_be result */ u32 crc32c_le; /* expected crc32c_le result */ -} test[] = +} const test[] __initconst = { {0x674bf11d, 0x00000038, 0x00000542, 0x0af6d466, 0xd8b6e4c1, 0xf6e93d6c}, {0x35c672c6, 0x0000003a, 0x000001aa, 0xc6d3dfba, 0x28aaf3ad, 0x0fe92aca}, -- 1.9.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
