[patch] ext2-fs filesystem corruption since 2.4.0-test6, fix

2001-04-10 Thread Ingo Molnar
the attached patch fixes the ext2-fs filesystem corruption that initially showed up during stress-tests running on Red Hat's internal testsystems, and which bug kept us busy for a long time. We suspect that a number of filesystem corruption bugs reported to l-k were caused by this bug too.

Re: No 100 HZ timer !

2001-04-10 Thread Alan Cox
Timers more precise than 100HZ aren't probably needed - as MIN_RTO is 0.2s and MIN_DELACK is 0.04s, TCP would hardly benefit from them. There are a considerable number of people who really do need 1Khz resolution. Midi is one of the example cases. That doesn't mean we have to go to a 1KHz

Re: [PATCH] Fix scsi_unblock_requests()

2001-04-10 Thread Alan Cox
In its current implementation, scsi_unblock_requests() simply clears host_self_blocked in the SCSI host struct. This means that either a transaction must complete or a new transaction Suppose the queue is unblocked from inside the functions called to process the request. In that situation
