f2fs: fix to build free nids from readaheaded nat pages When there is no enough free nids in free nid cache, we will try to readahead FREE_NID_PAGES:4 nat pages into page cache of meta_inode, then, reading nat entries in nat page for adding free nids to free nid cache. But when traversing all nat pages we readaheaded in a circulation, our exit condition is not set right, one more nat page will be scanned without readaheading, resulting worse read performance. This patch fixes to read the correct number nat pages to avoid bad performance. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
