    nilfs2: fix infinite loop in nilfs_palloc_freev function · 349dbc36
    Ryusuke Konishi authored
    After having applied commit 9954e7af ("nilfs2: add free
    entries count only if clear bit operation succeeded"), a free routine
    of nilfs came to fall into an infinite loop, outputting the same
    message endlessly:
    
     nilfs_palloc_freev: entry number 29497 already freed
     nilfs_palloc_freev: entry number 29497 already freed
     nilfs_palloc_freev: entry number 29497 already freed
     nilfs_palloc_freev: entry number 29497 already freed
     nilfs_palloc_freev: entry number 29497 already freed ...
    
    That patch broke the routine so that a loop counter is never updated
    in an abnormal state.  This fixes the regression.
