Subject: f2fs: don't check PAGE_SIZE again in sanity_check_raw_super()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d540e35d4e547776ea78d51f614ec38ed2824fbe;p=linux.git

f2fs: don't check PAGE_SIZE again in sanity_check_raw_super()

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().
