Subject: [GIT PULL] erofs fixes for 6.4-rc4

Hi Linus,

Could you consider these three patches for 6.4-rc4?

One patch addresses a null-ptr-deref issue reported by syzbot weeks
ago, which is caused by the new long xattr name prefix feature and
needs to be fixed.

The remaining two patches are minor cleanups to avoid unnecessary
compilation and adjust per-cpu kworker configuration.

Thanks,
Gao Xiang
