But, # the dump_page() itself accesses struct page to determine how to print # it, and therefore gets into a recursive loop. # # For example: # # dump_page() # __dump_page() # PageSlab(page) # PF_POISONED_CHECK(page) # VM_BUG_ON_PGFLAGS(PagePoisoned(page), page) # dump_page() recursion loop. # # Link: http://lkml.kernel.org/r/20180702180536.2552-1-pasha.tatashin@oracle.com # Fixes: f165b378bbdf ("mm: uninitialized struct page poisoning sanity checking") # Signed-off-by: Pavel Tatashin <pasha.tatashin@oracle.com> # Acked-by: Michal Hocko <mhocko@suse.com> # Cc: <stable@vger.kernel.org> # Signed-off-by: Andrew Morton <akpm@linux-foundation.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < git log --format=%s --max-count=1 fc36def997cfd6cbff3eda4f82853a5c311c5466 # < make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
