Hi,

2.1.30 sucks up system time (at least on my 486DX33 8MB test target).
When compiling a kernel, 2.1.30 spends almost 50% more time inside the
kernel than 2.1.29.

The problem is the change of search order in get_empty_inode(). Changing
i_prev back to i_next resolves the problem.

Ingo, wasn't this a performance change for NFS?

Regards,

markhe
