      kconfig: fix failing to generate auto.conf · 1b9e740a
      Jing Leng authored
      When the KCONFIG_AUTOCONFIG is specified (e.g. export \
      KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of
      include/config/ will not be created, so kconfig can't create deps
      files in it and auto.conf can't be generated.

      kfence: make test case compatible with run time set sample interval · 8913c610
      Peng Liu authored
      The parameter kfence_sample_interval can be set via boot parameter and
      late shell command, which is convenient for automated tests and KFENCE
      parameter optimization.  However, KFENCE test case just uses
      compile-time CONFIG_KFENCE_SAMPLE_INTERVAL, which will make KFENCE test
      case not run as users desired.  Export kfence_sample_interval, so that
      KFENCE test case can use run-time-set sample interval.

      In this example a slab allocation from __send_signal() caused a
      refilling and draining of a percpu objcg stock, resulted in a releasing
      of another non-related objcg.  Objcg release path requires taking the
      css_set_lock, which is used to synchronize objcg lists.
      
      This can create a circular dependency with the sighandler lock, which is
      taken with the locked css_set_lock by the freezer code (to freeze a
      task).
      
      In general it seems that using css_set_lock to synchronize objcg lists
      makes any slab allocations and deallocation with the locked css_set_lock
      and any intervened locks risky.
      
      To fix the problem and make the code more robust let's stop using
      css_set_lock to synchronize objcg lists and use a new dedicated spinlock
      instead.
