Hello, > kern :err : [ 187.461914] F2FS-fs (sda1): Swapfile does not align to section > commit 02eb84b96bc1b382dd138bf60724edbefe77b025 > Author: huangjianan@xxxxxxxx <huangjianan@xxxxxxxx> > Date: Mon Mar 1 12:58:44 2021 +0800 > f2fs: check if swapfile is section-alligned > If the swapfile isn't created by pin and fallocate, it can't be > guaranteed section-aligned, so it may be selected by f2fs gc.

I'm not sure what pin refers to? -- Thank you, Richard.
