To: linux-kernel; +Cc: rieserfs-list, david
I believe that the problem reported by David is caused by find_inode()
calling test(inode, data)
when the inode is in a transition state(I_LOCK|I_NEW|I_FREEING|I_CLEAR).
The test() call that used to
be called find actor is calling the underling filesystem with an Inode that
is not initialized yet or is
being deleted.
A simple change in find_inode() to move the code that already checks for
this transition state after
the call to test(), to be done before the call to test() will solve the
problem for inode deletion, and
adding a check for I_LOCK and waiting on new inode creation will fix it for
adding inodes.
