This is because the path is slow and it's important to verify that callers are really doing the right thing and recovering by specifying smaller orders rather than simply falling back to vmalloc(). The problem is that there is no way of suppressing the warning when the callers are doing the right thing. Patch 1 of this series allows the warning to be suppressed with __GFP_NOWARN. The second two patches suppress warnings generated by the profile= and the DCCP network protocol as those callers are recovering in a sensible fashion. kernel/profile.c | 5 +++-- mm/page_alloc.c | 4 +++- net/dccp/proto.c | 4 ++-- 3 files changed, 8 insertions(+), 5 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
