While working on my project, I think I ran into an error in a man page
for a function, VOP_ISLOCKED. The man page describes it as:
Test if the vnode vp is locked. A non-zero value is
the vnode is not locked, otherwise zero is returned.
I believe from what I've been able to tell, it is the opposite. A zero
is returned if the vnode is not locked and non-zero value is returned
if it is locked (the value representing the appropriate locks).
This is the test that I did to find this out:
printf("1bvp ISLOCKED = %d\n",VOP_ISLOCKED(bvp)); //should have been
locked at this point
printf("2bvp ISLOCKED = %d\n",VOP_ISLOCKED(bvp)); //should be
unlocked at this point
when I do dmesg I get the following results though
1bvp ISLOCKED = 2
2bvp ISLOCKED = 0
So as you can see I'm getting the opposite results that I expected.
This held up the progress of my project so if this is really wrong, as
I suspect, I'd like to fix it so it doesn't confuse anyone else. Can
someone confirm this or correct me if I am wrong somehow.
