Willy,
The link_path_walk fix in v2.4.30 is related to a reference counting bug triggered by "umount"...
As Christoph noted OpenAFS seems to be doing nasty things... it seems to play with dentries inode i_state directly? If that is the case, maybe it should define d_iput?
static inline void dentry_iput(struct dentry * dentry) { struct inode *inode = dentry->d_inode; if (inode) { dentry->d_inode = NULL; list_del_init(&dentry->d_alias); spin_unlock(&dcache_lock); if (dentry->d_op && dentry->d_op->d_iput) dentry->d_op->d_iput(dentry, inode);
