[PATCH] f2fs: forcibly migrate to secure space for zoned device file pinning

Posted by Daeho Jeong 2 months, 2 weeks ago

We need to migrate data blocks even though it is full to secure space
for zoned device file pinning.

Do you mean this, right?

do_garbage_collect(sbi, segno, &gc_list, FG_GC, true, false);

Oh, after ZUFS GC patches, we have six parameters on that. You're right.

static int do_garbage_collect(struct f2fs_sb_info *sbi,
                                unsigned int start_segno,
                                struct gc_inode_list *gc_list, int gc_type,
                                bool force_migrate)
