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.
