>From 272d7ef4611e64269fada0ea3021eece590118b9 Mon Sep 17 00:00:00 2001 From: Ethan Carter Edwards <et...@ethancedwards.com> Date: Sun, 22 Dec 2024 21:23:56 -0500 Subject: [PATCH] fs: erofs: xattr.c change kzalloc to kcalloc
Refactor xattr.c to use kcalloc instead of kzalloc when multiplying allocation size by count. This refactor prevents unintentional memory overflows. Discovered by checkpatch.pl.
