Subject: f2fs: avoid needless sync_inode_page when reading inline_data
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ae96e7bdd42739ef677a8a5d2d39d3eac5a4ff59;p=linux-beck.git

f2fs: avoid needless sync_inode_page when reading inline_data

In write_begin, if there is an inline_data, f2fs loads it into 0'th data page.
Since it's the read path, we don't need to sync its inode page.
