[PATCH v2] f2fs: reuse read_inline_data for f2fs_convert_inline_page

From: Shawn Lin
Date: Fri Feb 19 2016 - 03:07:39 EST


f2fs_convert_inline_page introduce what read_inline_data
already does for copying out the inline data from inode_page.
We can use read_inline_data instead to simplify the code.
