Message-ID: <20071203092607.GA22477@localhost.sw.ru> (raw)
Hi, Greg!
Commit ce2c9cb0259acd2aed184499ebe41ab00da13b25 aka
"kobject: remove the static array for the name" introduced memory leak
of a module name after modprobe/rmmod. Apparently for modules ->release
callback is NULL.
kobject_cleanup: ->release = 00000000, name = 'foo_sysctl'
