Subject: [PATCH 4/6] fix under-allocated kbuf size
Date: Wed, 16 Nov 2022 09:26:44 +0000	[thread overview]
Message-ID: <20221116092646.19919-5-e@80x24.org> (raw)
In-Reply-To: <20221116092646.19919-1-e@80x24.org>

kbuf is always `struct src_loc', not `struct alloc_hdr'.
Fortunately, nobody really needs PATH_MAX size for pathnames, so
this wasn't a problem in practice.
