      block: fix use-after-free bug in blk throttle code · 7ad58c02
      Jens Axboe 提交于
      blk_throtl_exit() frees the throttle data hanging off the queue
      in blk_cleanup_queue(), but blk_put_queue() will indirectly
      dereference this data when calling blk_sync_queue() which in
      turns calls throtl_shutdown_timer_wq().
      
      Fix this by moving the freeing of the throttle data to when
      the queue is truly being released, and post the call to
      blk_sync_queue().

      Revert "tty: Add a new file /proc/tty/consoles" · 6c2754c2
      Linus Torvalds 提交于
      This reverts commit f4a3e0bc.  Jiri
      Sladby points out that the tty structure we're using may already be
      gone, and Al Viro doesn't hold back in complaining about the random
      loading of 'filp->private_data' which doesn't have to be a pointer at
      all, nor does checking the magic field for TTY_MAGIC prove anything.
      
      Belated review by Al:
      
       "a) global variable depending on stdin of the last opener? Affecting
           output of read(2)? Really?
      
        b) iterator is broken; list should be locked in ->start(), unlocked in
           ->stop() and *NOT* unlocked/relocked in ->next()
      
        c) ->show() ought to do nothing in case of ->device == NULL, instead
           of skipping those in ->next()/->start()
      
        d) regardless of the merits of the bright idea about asterisk at that
           line in output *and* regardless of (a), the implementation is not
           only atrociously ugly, it's actually very likely to be a roothole.
           Verifying that Cthulhu knows what number happens to be address of a
           tty_struct by blindly dereferencing memory at that address...
           Ouch.
      
        Please revert that crap."
      
      And Christoph pipes in and NAK's the approach of walking fd tables etc
      too.  So it's pretty unanimous.

      nilfs2: eliminate sparse warning - "context imbalance" · 6b81e14e

      nilfs_segctor_kill_thread is only called inside sc_state_lock lock.
      sparse doesn't detect the context and warn "unexpected unlock".
      __acquires/__releases pretend to lock/unlock the sc_state_lock for sparse.

      Nilfs now can use sb->s_bdi to get backing_dev_info, so we use it
      instead of ns_bdi on the nilfs object and remove ns_bdi.

      nilfs2: change license of exported header file · c486f389
      Ryusuke Konishi 提交于
      This allows other projects to carry copies of the header file related
      to ABI and disk format (i.e. "nilfs2_fs.h") without it or distributors
      having to worry about effects on the project's overall license terms.
      It's also desired for switching the license of nilfs library to LGPL.
      
      Jiro SEKIBA pointed out these license issues (Message-ID:
      <87tylo7msw.wl%jir@sekiba.com>), and he suggested switching license of
      the library and nilfs2_fs.h to GNU Lesser General Public License.  We
      take in his suggestion to avoid the license issues.

      nilfs2: add bdev freeze/thaw support · 5beb6e0b
      Ryusuke Konishi 提交于
      Nilfs hasn't supported the freeze/thaw feature because it didn't work
      due to the peculiar design that multiple super block instances could
      be allocated for a device.  This limitation was removed by the patch
      "nilfs2: do not allocate multiple super block instances for a device".
      
      So now this adds the freeze/thaw support to nilfs.

      Ryusuke Konishi 提交于
      The current implementation doesn't mount snapshots with checkpoint
      numbers larger than INT_MAX since it uses match_int() for parsing
      "cp=" mount option.
      
      This uses simple_strtoull() for the conversion to resolve the issue.

      Ryusuke Konishi 提交于
      Nilfs object holds a back pointer to a writable super block instance
      in nilfs->ns_writer, and this became eliminable since sb is now made
      per device and all inodes have a valid pointer to it.
      
      This deletes the ns_writer pointer and a reader/writer semaphore
      protecting it.
