service outage or delays.
> hold the fsn/fsd lock
@kihwal Thanks for your comment. I tested to obtain quota information for
10w directories, and its holding lock time was about 300ms. Under normal
circumstances, our quota list is limited, I think it will not be particularly
high, this is just my guess.
In addition, I did a test to get only the Quota directory path, and the 10w
directory also took 20ms. We first get the path of the quota directory, and
then get the quota information through getQuotaUsage, is this better?
