[PATCH 3/3] populate: create fewer holes in directories and xattrs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

The same study of aging filesystem metadumps also showed that the rate
of file and xattr deletion is a lot lower than what this script does.
Decrease the deletion interval from every other file/name to every 19th
item to get us to a more reasonable 5% deletion rate, but with a prime
number. ;)
