Re: 2.6.5-mm1 [PATCH]

Hello,

Probably the least important email you'll receive all day, but...

>  shrink inode when quota is disabled

Could I suggest an alternate version, below? It limits the knowledge of
the CONFIG_QUOTA option to the quota header file, and still shrinks the
inode by two pointers. The only functional difference between this and
Matt Mackall's version is the below will still leave in a call to
memset, but with a zero length. On the plus side, it keeps fs/inode.c
free of preprocessor noise, which seems worth the trade-off.
