The patch titled Subject: atm: use pci_zalloc_consistent has been added to the -mm tree. Its filename is atm-use-pci_zalloc_consistent.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/atm-use-pci_zalloc_consistent.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/atm-use-pci_zalloc_consistent.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Joe Perches <joe@xxxxxxxxxxx> Subject: atm: use pci_zalloc_consistent Remove the now unnecessary memset too.
