ksplice-undo
KSPLICE-UNDO(8) Ksplice KSPLICE-UNDO(8)
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
", followed by a human-readable failure message,
to standard error.
