Subject: [PATCH 1/2] block: partitions: efi: report the right relation for last_usable_lba
Date: Fri, 21 Aug 2026 15:23:54 +0800 [thread overview]
Message-ID: <20260821072355.2006771-1-zhanxusheng@xiaomi.com> (raw)
From: Zhan Xusheng <zhanxusheng1024@gmail.com>
From: Zhan Xusheng <zhanxusheng@xiaomi.com>
The check rejects a header whose last_usable_lba is below its
first_usable_lba, but the message prints the two with ">" between them,
carried over from the preceding test against lastlba.
