[PATCH] EDAC: kobject/sysfs fixes
- After we unregister a kobject, wait for our kobject release method to call complete(). This causes us to wait until the kobject reference count reaches 0. Otherwise, a task accessing the EDAC sysfs interface can hold the reference count above 0 until after the EDAC module has been unloaded. When the reference count finally drops to 0, this will result in an attempt to call our release method inside the EDAC module after the module has already been unloaded. This isn't the best fix, since a process can get stuck sleeping forever uninterruptibly if the user does the following: rmmod my_module < /sys/my_sysfs/file I'll go back and implement a better fix later. However this should be ok for now. - Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather than from edac_mc_free(). Since edac_mc_add_mc() calls edac_create_sysfs_mci_device(), edac_mc_del_mc() should call edac_remove_sysfs_mci_device(). Signed-off-by: David S.
