8.11. Uninstalling the kernel patch module

Procedure

1. Select a kernel patch module:

   # kpatch list
   Loaded patch modules:
   kpatch_6_12_0_1_0_1 [enabled]
   
   Installed patch modules:
   kpatch_6_12_0_1_0_1 (6.12.0.el10_0.x86_64)
   …​

2. Uninstall the selected kernel patch module.

   # kpatch uninstall kpatch_6_12_0_1_0_1
   uninstalling kpatch_6_12_0_1_0_1 (6.12.0.el10_0.x86_64)

   • Note that the uninstalled kernel patch module is still loaded:

     # kpatch list
     Loaded patch modules:
     kpatch_6_12_0_1_0_1 [enabled]
     
     Installed patch modules:
     <NO_RESULT>

     When the selected module is uninstalled, the kernel remains patched until the next reboot, but the kernel patch module is removed from disk.

3. Reboot your system.

Verification

1. Verify that the kernel patch module is uninstalled:

   # kpatch list
   Loaded patch modules:
   …​

   This example output shows no loaded or installed kernel patch modules, therefore the kernel is not patched and the kernel live patching solution is not active.
