erofs: fix setting up pcluster for temporary pages
commit a30573b upstream. pcluster should be only set up for all managed pages instead of temporary pages. Since it currently uses page->mapping to identify, the impact is minor for now. [ Update: Vladimir reported the kernel log becomes polluted because PAGE_FLAGS_CHECK_AT_FREE flag(s) set if the page allocation debug option is enabled. ] Link: https://lore.kernel.org/r/20201022145724.27284-1-hsiangkao@aol.com Fixes: 5ddcee1 ("erofs: get rid of __stagingpage_alloc helper") Cc: <stable@vger.kernel.org> # 5.5+ Tested-by: Vladimir Zapolskiy <vladimir@tuxera.com> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Gao Xiang <hsiangkao@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
