I guess today is ridiculous ideas day. :-(

When are you guys going to understand that restricting dmesg *wording*
is never going to fly. It is going to be a losing game of whack-a-mole
for you. You can't really enforce it on people to stop using certain
words in dmesg just because it'll break your scripts. I can't believe
we're still *wasting* time talking about this insanity.

So let me point you in a better direction: have you guys heard of printk
loglevels? The number that gets prepended to each line in dmesg?


$ dmesg -r
...

<6>[    4.656173] i801_smbus 0000:00:1f.3: SMBus using PCI interrupt
<3>[    4.657280] irq: Invalid fwnode type (2) for irqdomain
<4>[    4.660181] ACPI Warning: SystemIO range 0x0000000000000428-0x000000000000042F conflicts with OpRegion 0x0000000000000400-0x000000000000047F (\_SB.PCI0.LPC.PMIO) (20170303/utaddress-247)
<6>[    4.662265] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

6 is KERN_INFO, 3 is KERN_ERR, 4 is KERN_WARNING and so on.

If you really want to look for errors and warnings, you should use those
loglevels. Like everyone else does. And if messages have the wrong
loglevels, they should be fixed.

This is how it should be done reliably - the stress being on *reliably*
- not by grepping for words.
