      ext4: code cleanup in mb_find_buddy() · 84b775a3
      Coly Li authored
      Current code calculate max no matter whether order is zero, it's
      unnecessary. This cleanup patch sets max to "1 << (e4b->bd_blkbits
      + 3)" only when order == 0.

      vfs: fix BUG_ON() in fs/namei.c:1461 · 3abb17e8
      Linus Torvalds authored
      When Al moved the nameidata_dentry_drop_rcu_maybe() call into the
      do_follow_link function in commit 844a3917 ("nothing in
      do_follow_link() is going to see RCU"), he mistakenly left the
      
      	BUG_ON(inode != path->dentry->d_inode);
      
      behind.  Which would otherwise be ok, but that BUG_ON() really needs to
      be _after_ dropping RCU, since the dentry isn't necessarily stable
      otherwise.
      
      So complete the code movement in that commit, and move the BUG_ON() into
      do_follow_link() too.  This means that we need to pass in 'inode' as an
      argument (just for this one use), but that's a small thing.  And
      eventually we may be confident enough in our path lookup that we can
      just remove the BUG_ON() and the unnecessary inode argument.
