Subject: [GIT PULL] erofs fixes for 5.16-rc1

Hi Linus,

Could you please consider these 2 small erofs patches?

One patch fixes an old corner case which can hardly reproduce
but cause unsafe pagevec reuse. It needs to be fixed right now.

Another patch is a trivial cleanup which gets rid of the unused
DELAYEDALLOC strategy which has already been replaced by TRYALLOC.

All commits have been in linux-next for a while and no merge
conflicts. I think no need to hold on these until 5.16-rc1 is
out and I could plan for 5.17 cleanup/development stuffs then...

Many thanks!
Gao Xiang
