Subject: [PATCH] smartd: added smartd.conf Directives -T and -s. The -T
Directive enables/disables Automatic Offline Testing. The -s Directive
enables/disables Attribute Autosave. Documentation and example configuration
file updated to agree.
Some revision of documentation to clarify the different between offline
testing and self-testing.

+Test: Enables S.M.A.R.T. automatic offline test which scans the drive
every four hours for disk defects. This command can be given during normal
system operation.
-S.M.A.R.T. provides three basic classes of testing. The so-called 'online'
-testing has no effect on the performance of the device. It
-is turned on by the '\-e' option. The offline testing, enabled by
-this '\-t' option, can, in principle, degrade the device performance. Normally,
-the disk will suspend any offline testing while disk accesses are
-taking place, then automatically resume them when the disk would
-otherwise be idle, so in practice it has little effect. The third
-class of testing is the 'self' testing; see below.
+Note that the S.M.A.R.T. automatic offline test command is listed as 'Obsolete'
+in every version of the ATA and ATA/ATAPI Specifications
+that I can find. However it is implemented and used by some
+vendors. [Good documentation can be found in IBM's Official
+Published Disk Specifications. For example the IBM Travelstar 40GNX
+Hard Disk Drive Specifications (Revision 1.1, 22 April 2002,
+Publication # 1541, Document S07N-7715-02) page 164.]
+
+S.M.A.R.T. provides three basic categories of testing. The first
+category, called 'online' testing, has no effect on the performance of
+the device. It is turned on by the '\-e' option.
+
+The second category of testing is called 'offline' testing. This type
+of test can, in principle, degrade the device performance. The '\-t'
+option causes this offline testing to be carried out, automatically,
+on a regular scheduled basis. Normally, the disk will suspend any
+offline testing while disk accesses are taking place, then
+automatically resume them when the disk would otherwise be idle, so in
+practice it has little effect. Note that a one-time offline test can
+also be carried out immediately upon receipt of a user command. See
+the '\-O' option below, which causes a one-time offline test to be
+carried out.
+
+Any errors detected in automatic or immediate offline testing will be
+shown in the S.M.A.R.T. error log, and will be reflected in the values
+of the S.M.A.R.T. attributes. These are visible with the '\-l' and '\-v' options.
+
+The third class of testing is the 'self' testing. This third type of
+test is only performed (immediately) when a command to run it is
+issued. The '\-S', '\-s', '\-X', '\-x', and '\-A' options below can
+be used to carry out such self-tests; please see below for further
+details.
+
+Any errors detected in the self testign will be shown in the
+S.M.A.R.T. self-test log, which can be examined using the '\-L'
+option.
-Any errors detected in the automatic offline testing will be shown in
