Subject: [PATCH 5.17 770/772] md: fix double free of io_acct_set bioset
From: Xiao Ni <xni@...hat.com>
commit 42b805af102471f53e3c7867b8c2b502ea4eef7e upstream.
Now io_acct_set is alloc and free in personality. Remove the codes that
free io_acct_set in md_free and md_stop.
Fixes: 0c031fd37f69 (md: Move alloc/free acct bioset in to personality)
