replace GFP_KERNEL with GFP_ATOMIC, as code while holding a spinlock should be atomic GFP_KERNEL may sleep and can cause deadlock, where as GFP_ATOMIC may fail but certainly avoids deadlock Signed-off-by: Saurabh Sengar <saurabh.truth@gmail.com> --- drivers/firmware/efi/vars.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/firmware/efi/vars.c b/drivers/firmware/efi/vars.c index 70a0fb1..c07de85 100644 --- a/drivers/firmware/efi/vars.c +++ b/drivers/firmware/efi/vars.c @@ -334,7 +334,7 @@ static void dup_variable_bug(efi_char16_t *str16, efi_guid_t *vendor_guid, */ efivar_wq_enabled = false; - str8 = kzalloc(len8, GFP_KERNEL); + str8 = kzalloc(len8, GFP_ATOMIC); if (!str8) return; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
