…rations.c Similar to file operation, directory operation performance is an important benchmark to file system in practice. * dircreate engine measures directories create performance * dirstat engine measures directories lookup performance * dirdelete engine measures directories delete performance Signed-off-by: friendy-su <friendy.su@sony.com>
|
Merged directory operation codes into fileoperation.c according to #1707 |
