[dm-devel] [PATCH 00/30] SLES resync, second try

[Hannes Reinecke]

Hi Christophe,

here as some patches which accumulated in my SLES repository.
Most are plain bugfixes, but there are some nasty issues fixed
with this:
- The conversion to libudev was a bit overzealous; originally
  we'd be skipping all devices which don't have a SCSI ID.
  With libudev we'd be including even those, making multipath
  claiming even USB flash disks 
  So I've implemented a new 'property' blacklist which will
  allow us to blacklist devices based on the udev property.
- dev_loss_tmo setting continues to be tricky, but this time
  I think we've got it sorted
- When using libudev to read attribute variables we'd be getting
  an automated caching from libudev. Which is nice, unless the
  data changed in between. So I'd have to go back an roll our
  own accessors, skipping libudev here.
- Ripping out 'getuid_callout' rendered all old configuration
  files still using in unworkable. So I've re-introduced it by
  marked it 'obsolete'.
- The confusion regarding directly reading from udev has been
  cleared up; I've added another patch for reading the 'state'
  attribute directly, too.

As usual, comments etc are welcome.
