      Revert "rtc: Expire alarms after the time is set." · f423fc62
      Linus Torvalds 提交于
      This reverts commit 93b2ec01.
      
      The call to "schedule_work()" in rtc_initialize_alarm() happens too
      early, and can cause oopses at bootup
      
      Neil Brown explains why we do it:
      
        "If you set an alarm in the future, then shutdown and boot again after
         that time, then you will end up with a timer_queue node which is in
         the past.
      
         When this happens the queue gets stuck.  That entry-in-the-past won't
         get removed until and interrupt happens and an interrupt won't happen
         because the RTC only triggers an interrupt when the alarm is "now".
      
         So you'll find that e.g.  "hwclock" will always tell you that
         'select' timed out.
      
         So we force the interrupt work to happen at the start just in case."
      
      and has a patch that convert it to do things in-process rather than with
      the worker thread, but right now it's too late to play around with this,
      so we just revert the patch that caused problems for now.

      Revert "rtc: Disable the alarm in the hardware" · 157e8bf8
      Linus Torvalds 提交于
      This reverts commit c0afabd3.
      
      It causes failures on Toshiba laptops - instead of disabling the alarm,
      it actually seems to enable it on the affected laptops, resulting in
      (for example) the laptop powering on automatically five minutes after
      shutdown.
      
      There's a patch for it that appears to work for at least some people,
      but it's too late to play around with this, so revert for now and try
      again in the next merge window.
      
      See for example

      hung_task: fix false positive during vfork · f9fab10b

      vfork parent uninterruptibly and unkillably waits for its child to

      security: Fix security_old_inode_init_security() when CONFIG_SECURITY is not set · 30e05324
      Jan Kara 提交于
      Commit 1e39f384 ("evm: fix build problems") makes the stub version
      of security_old_inode_init_security() return 0 when CONFIG_SECURITY is
      not set.
      
      But that makes callers such as reiserfs_security_init() assume that
      security_old_inode_init_security() has set name, value, and len
      arguments properly - but security_old_inode_init_security() left them
      uninitialized which then results in interesting failures.
      
      Revert security_old_inode_init_security() to the old behavior of
      returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this
      just fine.
      
      [ Also fixed the S_PRIVATE(inode) case of the actual non-stub
        security_old_inode_init_security() function to return EOPNOTSUPP
        for the same reason, as pointed out by Mimi Zohar.
      
        It got incorrectly changed to match the new function in commit
        fb88c2b6: "evm: fix security/security_old_init_security return
        code".   - Linus ]
