The definition and use of __GFP_REPEAT, __GFP_NOFAIL and __GFP_NORETRY in the core VM have somewhat differing comments as to their actual semantics. Annoyingly, the flags definition has inline and header comments, which might be interpreted as not being equivalent. Just add references to the header comments in the inline ones so they don't go out of sync in the future. In their use in __alloc_pages() clarify that the current implementation treats low-order allocations and __GFP_REPEAT allocations as distinct cases. To clarify, the flags' semantics are: __GFP_NORETRY means try no harder than one run through __alloc_pages __GFP_REPEAT means __GFP_NOFAIL __GFP_NOFAIL means repeat forever order <= PAGE_ALLOC_COSTLY_ORDER means __GFP_NOFAIL Signed-off-by: Nishanth Aravamudan <nacc@us.ibm.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
