Subject: mm/damon/core: do not call ops.cleanup() when destroying targets
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4614161fb6d4a56ead3e8e3e9cafa83a54747e4;p=thirdparty%2Fkernel%2Flinux.git

mm/damon/core: do not call ops.cleanup() when destroying targets

damon_operations.cleanup() is documented to be called for kdamond
termination, but also being called for targets destruction, which is done
for any damon_ctx destruction.  Nobody is using the callback for now,
though.  Remove the cleanup() call under the destruction.
