From e1175f02291141bbd924fc578299305fcde35855 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 5 Mar 2021 17:56:01 +0800 Subject: f2fs: fix to align to section for fallocate() on pinned file Now, fallocate() on a pinned file only allocates blocks which aligns to segment rather than section, so GC may try to migrate pinned file's block, and after several times of failure, pinned file's block could be migrated to other place, however user won't be aware of such condition, and then old obsolete block address may be readed/written incorrectly. To avoid such condition, let's try to allocate pinned file's blocks with section alignment.
