Hi Al,
All of my PowerPC boot tests are getting this after getting to user mode
(sometimes several times):

This is:
BUG_ON(inode->i_state != (I_FREEING | I_CLEAR));
in iput_final().
That BUG_ON was added by commit c0ae81f2 ("Make ->drop_inode() just
return whether inode needs to be dropped").
Has anyone seen this or something similar?
