|
Description:
|
|
A writable attribute that allows administrator to affect the
|
|
course of an existing transition. Writing 1 clears
|
|
TIF_PATCH_PENDING flag of all tasks and thus forces the tasks to
|
|
the patched or unpatched state. Administrator should not
|
|
use this feature without a clearance from a patch
|
|
distributor. Removal (rmmod) of patch modules is permanently
|
|
disabled when the feature is used. See
|
|
Documentation/livepatch/livepatch.rst for more information.

sympos number corresponding to the nth occurrence of the symbol

name in kallsyms for the patched object.

There are currently no such attributes.
