[Diskfilemon-announce] Announcing release 0.15.1

[Steve D. <st...@us...>]

Release 0.15.1 of the Disk File Monitor is available for download at
http://sourceforge.net/projects/diskfilemon/files/

This is a maintenance release of the Disk File Monitor.  It rolls up the
latest
bug fixes and enhancements.

Significant bug fixes:
* Install the dfm-ctrl script.
* Fix the hashing algorithm for the dfs hash.
* Rework the namehash code to use open hashing instead of closed hashing.
  Closed hashing runs the risk of running out of slots if a lot of files
  (greater than 64K) are being hit.
* Fix error messages.

Enhancements:
* Add the ability to build on kernels before 2.6.15.
* dfm-ctrl script enhancements
  - For the "layout", "exclude" and "verbose" commands display the current
value
    after it has been set, unless the quiet option is set.
  - Display the name of the verbose level along with its numerical value.
  - Add some safety checking to dfm-ctrl to make sure that dfm is loaded
before
    trying to execute commands.
* Performance improvements
  - Use finer grained locks, for example, one lock per hash table entry
instead
    of one lock for the whole hash table.
  - Save dentry pointers for the debugfs directories we create so that we
don't
    have to walk the parent directory's list of subdirs to find the
directory
    later.
  - Convert the spinlocks for the dri hash to rwlocks.
  - Better handling of strings by using string lengths.  For example,
comparing
    two strings is faster if their lengths are compared first.
