BTW, what exactly is the clear_inode and read_inode race that you mentioned? I am not familar with the locking model in Linux kernel. I found kernel_lock is held before ext3_rename/unlink/rmdir, so I think it's ok. But I do not understand how it is done in the path walk. Thanks, Yoshi -- Yoshihiro Tsuchiya
