2.4.15pre7: kernel: invalidate: busy buffer

2.4.15pre7: kernel: invalidate: busy buffer

[Samuli Suonpaa]

After booting with 2.4.15pre7 for the first time, I got a screeful of
messages saying: "invalidate: busy buffer".

>From my syslog:

Nov 20 21:20:27 oberon kernel: invalidate: busy buffer
Nov 20 21:20:27 oberon last message repeated 55 times
Nov 20 21:20:27 oberon kernel: invalidate: dirty buffer
Nov 20 21:20:27 oberon kernel: invalidate: busy buffer
Nov 20 21:20:27 oberon kernel: invalidate: dirty buffer
Nov 20 21:20:27 oberon kernel: invalidate: busy buffer
Nov 20 21:20:27 oberon kernel: invalidate: dirty buffer
Nov 20 21:20:27 oberon kernel: invalidate: busy buffer

Since I do not know what this should tell me, I'd appreciate if
somebody told me what this is all about. I can, of course, provide
more information if necessary. But since I don't have a clue on what
this would be related to (other that the printk seems to be in
buffer.c) I have no idea of what information might be useful.

It means you are using LVM on a new kernel.  Some day, the LVM code
will be changed so it doesn't do that.  For now it is not a real
error, just a warning.  It doesn't cause any real problems.

Cheers, Andreas
