      bootgraph: make the bootgraph script show async waiting time · d3f8ddea
      Arjan van de Ven authored
      It is useful for diagnosing boot performance to see where async function
      calls are waiting on serialization...  this patch adds this
      functionality to the bootgraph.pl script.
      
      The waiting time is shown as a half transparent, gray bar through the
      block that is waiting.

      libata: only ports >= 0 need to synchronize · fa853a48
      Arjan van de Ven authored
      In a discussio with Jeff Garzik, he mentioned that the serialization
      for the libata port probes only needs to be within the domain of a host.
      This means that for the first port of each host (with ID 0), we don't
      need to wait, so we can relax our serialization a little.

      libata: Add a per-host flag to opt-in into parallel port probes · 886ad09f
      Arjan van de Ven authored
      This patch adds a per host flag that allows drivers to opt in into
      having its busses scanned in parallel.
      
      Drivers that do not set this flag get their ports scanned in
      the "original" sequence.

      rbtree: add const qualifier to some functions · f4b477c4
      Artem Bityutskiy authored
      The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls
      take a pointer to an RB node or RB root. They do not change the
      pointed objects, so add a 'const' qualifier in order to make life
      of the users of these functions easier.
      
      Indeed, if I have my own constant pointer &const struct my_type *p,
      and I call 'rb_next(&p->rb)', I get a GCC warning:
      
      warning: passing argument 1 of ‘rb_next’ discards qualifiers from pointer target type

      LIS3LV02D: separate the core from HP ACPI API · cfce41a6
      Eric Piel authored
      The sensor can be accessed via various buses.  In particular, SPI, I²C
      and, on HP laptops, via a specific ACPI API (the only one currently
      supported).  Separate this latest platform from the core of the sensor
      driver to allow support for the other bus type.  The second, and more
      direct goal is actually to be able to merge this part with the
      hp-disk-leds driver, which has the same ACPI PNP number.

      filesystem freeze: add error handling of write_super_lockfs/unlockfs · c4be0c1d
      Takashi Sato authored
      Currently, ext3 in mainline Linux doesn't have the freeze feature which
      suspends write requests.  So, we cannot take a backup which keeps the
      filesystem's consistency with the storage device's features (snapshot and
      replication) while it is mounted.
      
      In many case, a commercial filesystem (e.g.  VxFS) has the freeze feature
      and it would be used to get the consistent backup.
      
      If Linux's standard filesystem ext3 has the freeze feature, we can do it
      without a commercial filesystem.
      
      So I have implemented the ioctls of the freeze feature.
      I think we can take the consistent backup with the following steps.
      1. Freeze the filesystem with the freeze ioctl.
      2. Separate the replication volume or create the snapshot
         with the storage device's feature.
      3. Unfreeze the filesystem with the unfreeze ioctl.
      4. Take the backup from the separated replication volume
         or the snapshot.
      
      This patch:
      
      VFS:
      Changed the type of write_super_lockfs and unlockfs from "void"
      to "int" so that they can return an error.
      Rename write_super_lockfs and unlockfs of the super block operation
      freeze_fs and unfreeze_fs to avoid a confusion.
      
      ext3, ext4, xfs, gfs2, jfs:
      Changed the type of write_super_lockfs and unlockfs from "void"
      to "int" so that write_super_lockfs returns an error if needed,
      and unlockfs always returns 0.
      
      reiserfs:
      Changed the type of write_super_lockfs and unlockfs from "void"
      to "int" so that they always return 0 (success) to keep a current behavior.
