Just hit this. Probably related to todays dcache changes ?

I'm not sure why, but the dcache.c line numbers don't match up.. This kernel was v3.3-rc7-14528-g29db10d which looked like..
229 */ 230 static void d_free(struct dentry *dentry) 231 { 232 BUG_ON(dentry->d_count); 233 this_cpu_dec(nr_dentry);
Hopefully that's close enough that that BUG_ON is the one that got hit.
