Merge tag 'erofs-for-6.8-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs fixes from Gao Xiang:

 - fix an infinite loop issue of sub-page compressed data support found
   with lengthy stress tests on a 64k-page arm64 VM

 - optimize the temporary buffer allocation for low-memory scenarios,
   which can reduce 20.21% on average under a heavy multi-app launch
   benchmark workload

 - get rid of unnecessary GFP_NOFS
