17 * What: /sys/kernel/debug/orangefs/kernel-debug
19 * Contact: Mike Marshall <hubcap@omnibond.com>
21 * Debug setting for the orangefs kernel module.
23 * Any of the keywords, or comma-separated lists
24 * of keywords, from debug-help can be catted to
25 * client-debug or kernel-debug.
27 * "none", "all" and "verbose" are special keywords
28 * for client-debug. Setting client-debug to "all"
29 * is kind of like trying to drink water from a
30 * fire hose, "verbose" triggers most of the same
31 * output except for the constant flow of output
32 * from the main wait loop.
34 * "none" and "all" are similar settings for kernel-debug
35 * no need for a "verbose".
