Kernel party trick

[coypu%sdf.org@localhost]

Have YOU ever wanted to quickly analyze locking on a long function?
well, wait no longer!

I have this function as a script:
$ cat ~/bin/fun
#!/bin/sh
awk "/^$@/,/^}/" *

Example usage:
$ fun lfs_truncate |grep -e mutex -e PUTPAGES
					mutex_enter(ovp->v_interlock);
					VOP_PUTPAGES(ovp,
			mutex_enter(&lfs_lock);
			mutex_exit(&lfs_lock);
			mutex_enter(ovp->v_interlock);
			error = VOP_PUTPAGES(ovp, round_page(length),
	mutex_enter(&lfs_lock);
	mutex_exit(&lfs_lock);

Pretty quick sanity check for a 412 line function!
