Description of problem:
Upstream ticket description:
"Recently, when trying to create/remove massive files/dirs(7x10^6) within a common directory, we found that as the creations go on, the time to create a single file/dir increases. After a series analysis, we found that this is due to the traversal of dirfrags the number of which increases exponentially as the number of subdirs/subfiles increases."
