From f5a53edcf01eae21dc3ef1845515229e8459e5cc Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 18 Oct 2019 10:06:40 -0700 Subject: f2fs: support aligned pinned file This patch supports 2MB-aligned pinned file, which can guarantee no GC at all by allocating fully valid 2MB segment. Check free segments by has_not_enough_free_secs() with large budget.
