| H A D | fsnotify.h | 4d8e7055 Sun May 05 04:15:49 CDT 2019 Amir Goldstein <amir73il@gmail.com> fsnotify: fix unlink performance regression
__fsnotify_parent() has an optimization in place to avoid unneeded
take_dentry_name_snapshot(). When fsnotify_nameremove() was changed
not to call __fsnotify_parent(), we left out the optimization.
Kernel test robot reported a 5% performance regression in concurrent
unlink() workload.
