[Juergen Hannken-Illjes <hannken%netbsd.org@localhost>]

Module Name:    src
Committed By:   hannken
Date:           Sat Jun 23 14:56:10 UTC 2007

Modified Files:
        src/sys/sys: param.h
        src/sys/ufs/ufs: quota.h ufs_quota.c

Log Message:
If a quota-enabled file system has 65536 active vnodes for one uid
the reference counter of the corresponding struct dquot will overflow.

Change the type of the reference counter from u_int16_t to u_int32_t and
add an assertion to check for overflow.

Observed and tested by Edgar Fuß.

Welcome to 4.99.21 (struct dquot and therefore struct inode changed layout)
