Subject: f2fs: read with READ_SYNC when getting dnode page
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=66d36a2944df461448159be5af13049dd2689e77;p=linux-beck.git

f2fs: read with READ_SYNC when getting dnode page

The get_node_page_ra tries to:
1. grab or read a target node page for the given nid,
2. then, call ra_node_page to read other adjacent node pages in advance.

So, when we try to read a target node page by #1, we should submit bio with
READ_SYNC instead of READA.
And, in #2, READA should be used.
