      bus: ti-sysc: Fix iterating over clocks · 2c81f0f6
      Tony Lindgren authored
      Commit d878970f ("bus: ti-sysc: Add separate functions for handling
      clocks") separated handling of optional clocks from the main clocks, but
      introduced an issue where we do not necessarily allocate a slot for both
      fck and ick clocks, but still assume fixed slots for enumerating over the
      clocks.
      
      Let's fix the issue by ensuring we always have slots for both fck and ick
      even if we don't use ick, and don't attempt to enumerate optional clocks
      if not allocated.
      
      In the long run we might want to simplify things a bit by only allocating
      space only for the optional clocks as we have only few devices with
      optional clocks.

      bus: ti-sysc: Fix missing reset delay handling · e709ed70
      Tony Lindgren authored
      We have dts property for "ti,sysc-delay-us", and we're using it, but the
      wait after OCP softreset only happens if devices are probed in legacy mode.
      
      Let's add a delay after writing the OCP softreset when specified.

       "orangefs: posix open permission checking...
      
        Orangefs has no open, and orangefs checks file permissions on each
        file access. Posix requires that file permissions be checked on open
        and nowhere else. Orangefs-through-the-kernel needs to seem posix
        compliant.
      
        The VFS opens files, even if the filesystem provides no method. We can
        see if a file was successfully opened for read and or for write by
        looking at file->f_mode.
      
        When writes are flowing from the page cache, file is no longer
        available. We can trust the VFS to have checked file->f_mode before
        writing to the page cache.
      
        The mode of a file might change between when it is opened and IO
        commences, or it might be created with an arbitrary mode.
      
        We'll make sure we don't hit EACCES during the IO stage by using
        UID 0"
      
      [ This is "posixish", but not a great solution in the long run, since a
        proper secure network server shouldn't really trust the client like this.
        But proper and secure POSIX behavior requires an open method and a
        resulting cookie for IO of some kind, or similar.    - Linus ]

      smb3: improve check for when we send the security descriptor context on create · 231e2a0b
      Steve French authored
      
      
      We had cases in the previous patch where we were sending the security
      descriptor context on SMB3 open (file create) in cases when we hadn't
      mounted with with "modefromsid" mount option.
      
      Add check for that mount flag before calling ad_sd_context in
      open init.
