      ide: use lock bitops for ports serialization (v2) · 5b31f855
      Bartlomiej Zolnierkiewicz authored
      * Add ->host_busy field to struct ide_host and use it's first bit
        together with lock bitops to provide new ports serialization method.
      
      * Convert core IDE code to use new ide_[un]lock_host() helpers.
      
        This removes the need for taking hwgroup->lock if host is already
        busy on serialized hosts and makes it possible to merge ide_hwgroup_t
        into ide_hwif_t (done in the later patch).
      
      * Remove no longer needed ide_hwgroup_t.busy and ide_[un]lock_hwgroup().
      
      * Update do_ide_request() documentation.
      
      v2:
      * ide_release_lock() should be called inside IDE_HFLAG_SERIALIZE check.
      
      * Add ide_hwif_t.busy flag and ide_[un]lock_port() for serializing
        devices on a port.

      ide: remove hwgroup->hwif and {drive,hwif}->next · efe0397e
      Bartlomiej Zolnierkiewicz authored
      * Add 'int port_count' field to ide_hwgroup_t to keep the track
        of the number of ports in the hwgroup.  Then update init_irq()
        and ide_remove_port_from_hwgroup() to use it.
      
      * Remove no longer needed hwgroup->hwif, {drive,hwif}->next,
        ide_add_drive_to_hwgroup() and ide_remove_drive_from_hwgroup()
        (hwgroup->drive now only denotes the currently active device
         in the hwgroup).
      
      * Update locking documentation in <linux/ide.h>.
      
      While at it:
      
      * Rename ->drive field in ide_hwgroup_t to ->cur_dev.
      
      * Use __func__ in ide_timer_expiry().

      ide: fix LOCKDEP warning · b46f205d
      Bartlomiej Zolnierkiewicz authored
      commit 295f0004 ("ide: don't execute
      the next queued command from the hard-IRQ context") overlooked that
      ide_do_drive_cmd() (used for REQUEST SENSE command handling) may still
      invoke do_ide_request() (->request_fn) in the hard-IRQ context through
      blk_start_queueing().  This resulted in a LOCKDEP warning after commit
      b599bc7a1199419e122cb2e9ec6b0fa2cfbbc17b ("ide: use per-device request
      queue locks (v2)").
      
      Since calling blk_start_queuing() in ide_do_drive_cmd() doesn't make
      much sense as the port is already marked as busy (so the execution of
      the new command will be deferred anyway) then just remove it fixing
      LOCKDEP warning and saving some CPU cycles at the same time.

      dm: add name and uuid to sysfs · 784aae73
      Milan Broz authored
      Implement simple read-only sysfs entry for device-mapper block device.
      
      This patch adds a simple sysfs directory named "dm" under block device
      properties and implements
      	- name attribute (string containing mapped device name)
      	- uuid attribute (string containing UUID, or empty string if not set)
      
      The kobject is embedded in mapped_device struct, so no additional
      memory allocation is needed for initializing sysfs entry.
      
      During the processing of sysfs attribute we need to lock mapped device
      which is done by a new function dm_get_from_kobj, which returns the md
      associated with kobject and increases the usage count.
      
      Each 'show attribute' function is responsible for its own locking.

      dm table: rework reference counting · d5816876
      Mikulas Patocka authored
      Rework table reference counting.
      
      The existing code uses a reference counter. When the last reference is
      dropped and the counter reaches zero, the table destructor is called.
      Table reference counters are acquired/released from upcalls from other
      kernel code (dm_any_congested, dm_merge_bvec, dm_unplug_all).
      If the reference counter reaches zero in one of the upcalls, the table
      destructor is called from almost random kernel code.
      
      This leads to various problems:
      * dm_any_congested being called under a spinlock, which calls the
        destructor, which calls some sleeping function.
      * the destructor attempting to take a lock that is already taken by the
        same process.
      * stale reference from some other kernel code keeps the table
        constructed, which keeps some devices open, even after successful
        return from "dmsetup remove". This can confuse lvm and prevent closing
        of underlying devices or reusing device minor numbers.
      
      The patch changes reference counting so that the table destructor can be
      called only at predetermined places.
      
      The table has always exactly one reference from either mapped_device->map
      or hash_cell->new_map. After this patch, this reference is not counted
      in table->holders.  A pair of dm_create_table/dm_destroy_table functions
      is used for table creation/destruction.
      
      Temporary references from the other code increase table->holders. A pair
      of dm_table_get/dm_table_put functions is used to manipulate it.
      
      When the table is about to be destroyed, we wait for table->holders to
      reach 0. Then, we call the table destructor.  We use active waiting with
      msleep(1), because the situation happens rarely (to one user in 5 years)
      and removing the device isn't performance-critical task: the user doesn't
      care if it takes one tick more or not.
      
      This way, the destructor is called only at specific points
      (dm_table_destroy function) and the above problems associated with lazy
      destruction can't happen.
      
      Finally remove the temporary protection added to dm_any_congested().

      dm: support barriers on simple devices · ab4c1424

      Implement barrier support for single device DM devices
      
      This patch implements barrier support in DM for the common case of dm linear
      just remapping a single underlying device. In this case we can safely
      pass the barrier through because there can be no reordering between
      devices.
      
       NB. Any DM device might cease to support barriers if it gets
           reconfigured so code must continue to allow for a possible
           -EOPNOTSUPP on every barrier bio submitted.  - agk

      dm request: extend target interface · 7d76345d
      Kiyoshi Ueda authored
      This patch adds the following target interfaces for request-based dm.
      
        map_rq    : for mapping a request
      
        rq_end_io : for finishing a request
      
        busy      : for avoiding performance regression from bio-based dm.
                    Target can tell dm core not to map requests now, and
                    that may help requests in the block layer queue to be
                    bigger by I/O merging.
                    In bio-based dm, this behavior is done by device
                    drivers managing the block layer queue.
                    But in request-based dm, dm core has to do that
                    since dm core manages the block layer queue.

      dm: consolidate target deregistration error handling · 10d3bd09
      Mikulas Patocka authored
      Change dm_unregister_target to return void and use BUG() for error
      reporting.
      
      dm_unregister_target can only fail because of programming bug in the

      This patch changes unregister_target to return void and use BUG if
      someone tries to unregister non-registered target or unregister target
      that is in use.
      
      This patch removes code duplication (testing of error codes in all dm
      targets) and reports bugs in just one place, in dm_unregister_target. In
      some target drivers, these return codes were ignored, which could lead
      to a situation where bugs could be missed.

      Always increase the error count when I/O on a leg of a mirror fails.
      
      The error count is used to decide whether to select an alternative

      error count is not updated and the bio can get requeued forever by the
      read callback.
      
      Fix it by increasing error_count before the handle_errors feature

      igb: fix anoying type mismatch warning on rx/tx queue sizing · e42e4ba0
      Linus Torvalds authored
      When using "min()", the types of both sides should match.  With the cpu
      mask changes, the type of num_online_cpus() will now depend on config
      options. Use "min_t()" with an explicit type instead.
      
      And make the rx/tx case look the same too, just for sanity.
