+# Client - thread-safe or not
+#   --disable-thread-safety : chooses null or posix locking mechanism
+#   For applications that know they are not multi-threaded, or choose
+#   to handle locking themselves, this configure option can be used to
+#   slightly decrease library-induced latency by removing the locking.
+#
+# Client - job threading
+#   libpvfs2-threaded.{so,a} with __PVFS2_JOB_THREADED__
+#   This option causes the client library to spawn an extra thread
+#   to handle network communications.  In this way, it is possible
+#   that the library can handle new and completed requests from
+#   the application while also interacting with the network.
+#
+#   These separate libraries can not be built using the existing
+#   configure mechanism.  They are only built if required by the
+#   kernel module helper.
+#
+# Server - three options:
+#   trove
+#     (hack Makefile.in)
+#   job
+#     (hack Makefile.in)
+#   aio
+#     --disable-aio-threaded-callbacks
+#
+#   Trove (storage) and job threading in the server are implemented
+#   using #defines, but not exported through the configure mechanism.
+#   AIO threaded callbacks are a separate thread used in conjunction
+#   with trove, and can be disabled through a configure option as
+#   AIO has been found to be buggy on many systems.
+#
+#
+# Kernel module helper - job threading
+#   --enable-threaded-kmod-helper
+#
+#   This is a special client that "helps" applications that access PVFS
+#   through the kernel using normal VFS calls (e.g. "ls").  This
+#   configure options builds it using __PVFS2_JOB_THREADED__ as described
+#   above.  That enables a thread for the network layer and a thread
+#   for the kernel interface.  This has the potential to increase the
+#   rate at which concurrent operations are processed, but has the potential
+#   drawback of somewhat higher overhead for a single operation and lack
+#   of testing.
+#
+#   Enabling this options causes one of libpvfs2-threaded.{so,a} to be

-# Threading options.
-#
-# Client - thread-safe or not
-#   --disable-thread-safety : chooses null or posix locking mechanism
-#   For applications that know they are not multi-threaded, or choose
-#   to handle locking themselves, this configure option can be used to
-#   slightly decrease library-induced latency by removing the locking.
-#
-# Client - job threading
-#   libpvfs2-threaded.{so,a} with __PVFS2_JOB_THREADED__
-#   This option causes the client library to spawn an extra thread
-#   to handle network communications.  In this way, it is possible
-#   that the library can handle new and completed requests from
-#   the application while also interacting with the network.
-#
-#   These separate libraries can not be built using the existing
-#   configure mechanism.  They are only built if required by the
-#   kernel module helper.
-#
-# Server - three options:
-#   trove
-#     (hack Makefile.in)
-#   job
-#     (hack Makefile.in)
-#   aio
-#     --disable-aio-threaded-callbacks
-#
-#   Trove (storage) and job threading in the server are implemented
-#   using #defines, but not exported through the configure mechanism.
-#   AIO threaded callbacks are a separate thread used in conjunction
-#   with trove, and can be disabled through a configure option as
-#   AIO has been found to be buggy on many systems.
-#
-#
-# Kernel module helper - job threading
-#   --enable-threaded-kmod-helper
-#
-#   This is a special client that "helps" applications that access PVFS
-#   through the kernel using normal VFS calls (e.g. "ls").  This
-#   configure options builds it using __PVFS2_JOB_THREADED__ as described
-#   above.  That enables a thread for the network layer and a thread
-#   for the kernel interface.  This has the potential to increase the
-#   rate at which concurrent operations are processed, but has the potential
-#   drawback of somewhat higher overhead for a single operation and lack
-#   of testing.
-#
-#   Enabling this options causes one of libpvfs2-threaded.{so,a} to be
-#   built, depending on --enable-shared and --enable-static.  If both are
-#   enabled, the shared library takes precedence.

-    =============================
-    --enable-redhat24         (if you are using a redhat provided 2.4 kernel)
-    --disable-redhat24        (if you are using a stock kernel.org kernel)

-    Also pick one of the next two options.  You should probably enable the
-    workaround if you are using RedHat EL 3 prior to update 2.  Otherwise it
-    is probably safer (and higher performance) to disable it:
-    =============================
