Subject: [PATCH v3 0/3] kprobes: Remove MODULES dependency
Date: Wed, 15 Jul 2020 01:32:26 +0300 [thread overview]
Message-ID: <20200714223239.1543716-1-jarkko.sakkinen@linux.intel.com> (raw)
Remove MODULES dependency and migrate from module_alloc to the new
text_alloc() API Right now one has to compile LKM support only to enable
kprobes. With this change applied, it is somewhat easier to create
custom test kernel's with a proper debugging capabilities, thus making
Linux more developer friendly.
Jarkko Sakkinen (3):
kprobes: Add text_alloc() and text_free()
module: Add lock_modules() and unlock_modules()
kprobes: Flag out CONFIG_MODULES dependent code
