f2fs: fix incorrect upper bound when iterating inode mapping tree
1. Inode mapping tree can index page in range of [0, ULONG_MAX], however, in some places, f2fs only search or iterate page in ragne of [0, LONG_MAX], result in miss hitting in page cache. 2. filemap_fdatawait_range accepts range parameters in unit of bytes, so the max range it covers should be [0, LLONG_MAX], if we use [0, LONG_MAX] as range for waiting on writeback, big number of pages will not be covered. This patch corrects above two issues. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
