From 135e541ae8f3f166453177f1a94a0ff1f86ce30f Mon Sep 17 00:00:00 2001 From: Zeng Chi Date: Wed, 5 Nov 2025 10:39:25 +0800 Subject: [PATCH] lib/alloc_tag: use %pe format specifier The %pe format specifier is designed to print error pointers. It prints a symbolic error name (eg. -EINVAL) and it makes the code simpler by omitting PTR_ERR(); This patch fixes this cocci report: lib/alloc_tag.c:776:63-70: WARNING: Consider using %pe to print PTR_ERR() Link: https://lkml.kernel.org/r/20251105023925.1447482-1-zeng_chi911@163.com Signed-off-by: Zeng Chi Acked-by: SeongJae Park Acked-by: Suren Baghdasaryan Cc: Kent Overstreet Signed-off-by: Andrew Morton --- lib/alloc_tag.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/alloc_tag.c b/lib/alloc_tag.c index f26456988445..27fee57a5c91 100644 --- a/lib/alloc_tag.c +++ b/lib/alloc_tag.c @@ -845,7 +845,7 @@ static int __init alloc_tag_init(void) alloc_tag_cttype = codetag_register_type(&desc); if (IS_ERR(alloc_tag_cttype)) { - pr_err("Allocation tags registration failed, errno = %ld\n", PTR_ERR(alloc_tag_cttype)); + pr_err("Allocation tags registration failed, errno = %pe\n", alloc_tag_cttype); free_mod_tags_mem(); shutdown_mem_profiling(true); return PTR_ERR(alloc_tag_cttype);
