NAME

       ksplice-undo - Undo a Ksplice update that has been applied to the running kernel

SYNOPSIS

       ksplice-undo [OPTIONS] KSPLICE_ID

DESCRIPTION

       ksplice-undo takes as input a Ksplice identification tag, as reported by ksplice-view(8),
       and it reverses that update within the running binary kernel.

OPTIONS

       --debug Reverses the update with debugging output enabled.  Recommended only for
               debugging.

       --debugfile=filename
               Sets the location where debugging output should be saved.  Implies --debug.

       --raw-errors
               Print only raw error information designed to be machine-readable on standard error
               (standard output is still intended to be human-readable).  If ksplice-undo fails
               due to an error from the Ksplice kernel modules, the first line on standard error
               will be a Ksplice abort code (see the Ksplice source code for documentation on
               these codes).  Further lines will vary depending on the abort code.  If ksplice-
               undo fails for any other reason, it will output the line "OTHER\n", followed by a
               human-readable failure message, to standard error.
