From: Tejun Heo <tj@kernel.org> mainline inclusion from mainline-v6.12-rc1 commit b651d7c39289850b5a0a2c67231dd36117340a2e category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8335 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- alloc_exit_info() calls kcalloc() but puts in the size of the element as the first argument which triggers the following gcc warning: kernel/sched/ext.c:3815:32: warning: ‘kmalloc_array_noprof’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Wcalloc-transposed-args] Fix it by swapping the positions of the first two arguments. No functional changes.
