    f2fs: avoid to read inline data except first page · 04a17fb1
    Chao Yu authored
    Here is a case which could read inline page data not from first page.
    1. write inline data
    2. lseek to offset 4096
    3. read 4096 bytes from offset 4096
    	(read_inline_data read inline data page to non-first page,
    	And previously VFS has add this page to page cache)
    4. ftruncate offset 8192
    5. read 4096 bytes from offset 4096
    	(we meet this updated page with inline data in cache)
    So we should leave this page with inited data and uptodate flag
    for this case.
    Change log from v1:
     o fix a deadlock bug
