Any chance of a printk() when a user's file write is stopped due to
hitting a hard quota? Would be a nice thing to have
logged. Although perhaps for messages like this and other future
messages, we might consider a new log message reporting scheme.
Be _really_ careful with this one. For many months we had to bother
sun endlessly because Solaris in fact did this, so if some stupid user
exceeded his quota and his process was just poorly written and kept on
trying the writes etc. your machine goes into %99 system time doing
console output.
