[PATCH] clockevents: remove bad designed sysfs support for now

291bc047 · Thomas Gleixner <[email protected]> · 2007-03-26 11:21:08 +02:00

The current sysfs support of clockevents does not obey the "only one
value per file" rule.

The real fix is not 2.6.21 material. Therefor remove the sysfs support
for now.
