[PATCH 0/4] Fix problems related to removal of UHCI hardware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greg:

The following series of patches fixes a bunch of problems that crop up
when a UHCI host controller is unexpectedly removed from a running
system.  The people at Stratus Technologies identified many of these
problems when testing their fault-tolerant (automatic failover)  
servers.  The problems have been reported in Red Hat's Bugzilla
#579093.  With these patches, the Stratus tests complete successfully.

I won't bother to describe the individual patches here; each has its 
own description.  Three of them are changes to usbcore; oddly enough 
only minimal changes were needed in uhci-hcd.

None of these fixes are critical in any sense.  Everybody has been 
running perfectly well without them for many years; thus they do not 
need to go into 2.6.35 or the stable kernels.  (However the Red Hat 
people may want to include them in the current RHEL kernel.)

Patch 2/4 in this series supersedes the patch that Robert Evans
submitted earlier.  I realized that the test at the start of
usb_hcd_poll_rh_status() could be made reliable, which is better than
removing it entirely.
