[PATCH 4/4] jffs2: Standardize JFFS_ uses

Joe Perches
2012-02-15T23:58:24Z

Use pr_<level> to prefix KBUILD_MODNAME via pr_fmt.

Remove obfuscating defines and use constants in pr_<level>
No need for a do {} while (0) for single statements.

Form of JFFS_<LEVEL> output changes from
"JFFS2 notice: " to "jffs2: notice: "

Added pr_fmt to xattr.c
