      block: Free queue resources at blk_release_queue() · 777eb1bf
      Hannes Reinecke authored
      A kernel crash is observed when a mounted ext3/ext4 filesystem is
      physically removed. The problem is that blk_cleanup_queue() frees up
      some resources eg by calling elevator_exit(), which are not checked for
      in normal operation. So we should rather move these calls to the
      destructor function blk_release_queue() as at that point all remaining
      references are gone. However, in doing so we have to ensure that any
      externally supplied queue_lock is disconnected as the driver might free
      up the lock after the call of blk_cleanup_queue(),

      vfs: remove LOOKUP_NO_AUTOMOUNT flag · b6c8069d
      Linus Torvalds authored
      That flag no longer makes sense, since we don't look up automount points
      as eagerly any more.  Additionally, it turns out that the NO_AUTOMOUNT
      handling was buggy to begin with: it would avoid automounting even for
      cases where we really *needed* to do the automount handling, and could
      return ENOENT for autofs entries that hadn't been instantiated yet.
      
      With our new non-eager automount semantics, one discussion has been
      about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the
      newfstatat() and fstatat64() system calls), but it's probably not worth
      it: you can always force at least directory automounting by simply
      adding the final '/' to the filename, which works for *all* of the stat
      family system calls, old and new.
      
      So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a
      result of our bad default behavior.

      ASoC: ssm2602: Re-enable oscillator after suspend · 9058020c
      Lars-Peter Clausen authored
      Currently the the internal oscillator is powered down when entering BIAS_OFF
      state, but not re-enabled when going back to BIAS_STANDBY. As a result the
      CODEC will stop working after suspend if the internal oscillator is used to
      generate the sysclock signal. This patch fixes it by clearing the appropriate
      bit in the power down register when the CODEC is re-enabled.

      VFS: Fix the remaining automounter semantics regressions · 815d405c
      Trond Myklebust authored
      The concensus seems to be that system calls such as stat() etc should
      not trigger an automount.  Neither should the l* versions.
      
      This patch therefore adds a LOOKUP_AUTOMOUNT flag to tag those lookups
      that _should_ trigger an automount on the last path element.

      [ Edited to leave out the cases that are already covered by LOOKUP_OPEN,
        LOOKUP_DIRECTORY and LOOKUP_CREATE - all of which also fundamentally
        force automounting for their own reasons   - Linus ]

      vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag · d94c177b
      Linus Torvalds authored
      Since we've now turned around and made LOOKUP_FOLLOW *not* force an
      automount, we want to add the ability to force an automount event on
      lookup even if we don't happen to have one of the other flags that force
      it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..)
      
      Most cases will never want to use this, since you'd normally want to
      delay automounting as long as possible, which usually implies
      LOOKUP_OPEN (when we open a file or directory, we really cannot avoid
      the automount any more).
      
      But Trond argued sufficiently forcefully that at a minimum bind mounting
      a file and quotactl will want to force the automount lookup.  Some other
      cases (like nfs_follow_remote_path()) could use it too, although
      LOOKUP_DIRECTORY would work there as well.
      
      This commit just adds the flag and logic, no users yet, though.  It also
      doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and
      was made irrelevant by the same change that made us not follow on
      LOOKUP_FOLLOW.
