The patch titled Subject: nilfs2: Use a more common logging style has been added to the -mm tree. Its filename is nilfs2-use-a-more-common-logging-style.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/nilfs2-use-a-more-common-logging-style.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/nilfs2-use-a-more-common-logging-style.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/process/submit-checklist.rst 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: nilfs2: Use a more common logging style Add macros for nilfs_<level>(sb, fmt, ...) and convert the uses of 'nilfs_msg(sb, KERN_<LEVEL>, ...)' to 'nilfs_<level>(sb, ...)' so nilfs2 uses a logging style more like the typical kernel logging style.
