From: Jia Yang <redacted> [ Upstream commit 10d0786b39b3b91c4fbf8c2926e97ab456a4eea1 ] This reverts commit 957fa47823dfe449c5a15a944e4e7a299a6601db. The patch "f2fs: Fix indefinite loop in f2fs_gc()" v1 and v4 are all merged. Patch v4 is test info for patch v1. Patch v1 doesn't work and may cause that sbi->cur_victim_sec can't be resetted to NULL_SEGNO, which makes SSR unable to get segment of sbi->cur_victim_sec. So it should be reverted.
