cmogstored is an alternative implementation of the "mogstored" storage
component of MogileFS.  cmogstored is implemented in C and does not use
Perl at runtime.  cmogstored is the only component you need to install
on a MogileFS storage node.


    The big feature in this release is "devNNN/usage" are served
    from memory, allowing up-to-date usage information even
    unwritable/unreadable filesystems.

    This can also be used to reduce spinups and wear on HDDs.

    "devNNN/usage" files are still updated on the FS by default for
    compatibility with existing HTTP servers, but admins may wish
    to disable updates to them by removing all permissions from
    the "usage" files:

            chmod 0000 $MOG_DOCROOT/dev*/usage

    Filesystem errors from the sendfile(2) syscalls are also
    logged to syslog.  There's also a bugfix for zombies for
    libkqueue-on-epoll users, but that doesn't affect native
    kqueue users on *BSDs.

    And the usual round of gnulib, minor doc and style updates.

    18 changes since v1.6.0:

          cmogstored.h: remove unused mog_file.mmptr member
          doc: documentation for ioq
          doc: further comment updates around ioq
