SubjectRe: [PATCH 1/1] mm: compaction: avoid fast_isolate_around() to set pageblock_skip on reserved pages

NOTE: this line will have to become "likely(page &&
!PageReserved(page))" to handle the case of non contiguous zones,
since pageblock_pfn_to_page might return NULL in that case.. I noticed
right after sending, but I'll wait some feedback before resending the
correction in case it gets fixed in another way.
