Subject: [PATCH 2/2] f2fs: don't check PAGE_SIZE again in sanity_check_raw_super()
Date: Mon, 7 Dec 2020 18:59:34 +0800 [thread overview]
Message-ID: <1607338774-8541-2-git-send-email-liush@allwinnertech.com> (raw)
In-Reply-To: <1607338774-8541-1-git-send-email-liush@allwinnertech.com>
From: Yangtao Li <tiny.windzz@gmail.com>
Many flash devices read and write a single IO based on a multiple
of 4KB, and we support only 4KB page cache size now.
Since we already check page size in init_f2fs_fs(), so remove page
size check in sanity_check_raw_super().
