Re: [f2fs-dev] [PATCH v3] f2fs: retry to update the inode page given EIO

[Jaegeuk Kim <jaegeuk@kernel.org>]

In f2fs_update_inode_page, f2fs_get_node_page handles EIO along with
f2fs_handle_page_eio that stops checkpoint, if the disk couldn't be recovered.
As a result, we don't need to stop checkpoint right away given single EIO.

 Change log from v2:
  - set EIO to cover the case of data corruption given by buggy UFS driver
