[PATCH 0/4] ublk: improve handling of saturated queues when ublk server exits

by Uday Shankar

This set aims to reduce the long delay in applications reacting to ublk server exit in the case of a "fully saturated" queue, i.e. one for which all I/Os are outstanding to the ublk server. The first few patches fix some minor issues in the ublk selftests, and the last patch contains the main work and a test to validate it.

[PATCH net] selftests: tc-testing: fix nat regex matching

by Pedro Tammela

In iproute 6.14, the nat ip mask logic was fixed to remove a undefined behaviour. So now instead of reporting '0.0.0.0/32' on x86 and potentially '0.0.0.0/0' in other platforms, it reports '0.0.0.0/0' in all platforms.

[PATCH] selftest: rtc: skip some tests if the alarm only supports minutes

by Wolfram Sang

There are alarms which have only minute-granularity. The RTC core already has a flag to describe them. Use this flag to skip tests which require the alarm to support seconds.

Output now looks like this: # RUN rtc.alarm_alm_set ... # SKIP Skipping test since alarms has only minute granularity. # OK rtc.alarm_alm_set ok 5 rtc.alarm_alm_set # SKIP Skipping test since alarms has only minute granularity.
