      udf: Remove unused s_extLength from udf_bitmap · 288be96d
      Jan Kara authored
      s_extLength was assigned to but the value was never really used. So
      just remove the field.

      udf: Make s_block_bitmap standard array · c60305b5
      Jan Kara authored
      struct udf_bitmap has array of buffer pointers attached to it. The code
      unnecessarily used s_block_bitmap as a pointer to the array instead of
      the standard trick of using 0 length array in the declaration. Change
      that to make code more readable and actually shrink the structure by one
      pointer.

      udf: Fix bitmap overflow on large filesystems with small block size · 89b1f39e
      Jan Kara authored
      For large UDF filesystems with 512-byte blocks the number of necessary
      bitmap blocks is larger than 2^16 so s_nr_groups in udf_bitmap overflows
      (the number will overflow for filesystems larger than 128 GB with
      512-byte blocks). That results in ENOSPC errors despite the filesystem
      has plenty of free space.
      
      Fix the problem by changing s_nr_groups' type to 'int'. That is enough
      even for filesystems 2^32 blocks (UDF maximum) and 512-byte blocksize.

      udf: add extent cache support in case of file reading · 99600051
      Namjae Jeon authored
      This patch implements extent caching in case of file reading.
      While reading a file, currently, UDF reads metadata serially
      which takes a lot of time depending on the number of extents present
      in the file. Caching last accessd extent improves metadata read time.
      Instead of reading file metadata from start, now we read from
      the cached extent.
      
      This patch considerably improves the time spent by CPU in kernel mode.
      For example, while reading a 10.9 GB file using dd:
      Time before applying patch:
      11677022208 bytes (10.9GB) copied, 1529.748921 seconds, 7.3MB/s

      USB: io_ti: Fix NULL dereference in chase_port() · 1ee0a224
      Wolfgang Frisch authored
      The tty is NULL when the port is hanging up.
      chase_port() needs to check for this.
      
      This patch is intended for stable series.
      The behavior was observed and tested in Linux 3.2 and 3.7.1.
      
      Johan Hovold submitted a more elaborate patch for the mainline kernel.

      staging/sb105x: PARPORT config is not good enough must use PARPORT_PC · 7dfc8331
      Steven Rostedt authored
      The sb105x driver calls parport_pc_probe_port() which isn't defined if
      PARPORT_PC isn't enabled. Protecting it with CONFIG_PARPORT is not good
      enough, must protect it with CONFIG_PARPORT_PC.

      Tormod Volden authored
      Commit 2e254212 broke listing of available network names, since it
      clamped the length of the returned SSID to WLAN_BSSID_LEN (6) instead of
      WLAN_SSID_MAXLEN (32).

        Two tiny fixes
        * A build warning fix due to signed / unsigned comparison
