[PATCHSET 0/3] xfs_db: create names with colliding hashes

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

 



Hi all,

While we're on the topic of directory entry naming, create a couple of
new debugger commands to create directory or xattr names that have the
same name hash.  This enables further testing of that aspect of the
dabtree code, which in turn enables us to perform worst case performance
analysis of the parent pointers code.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
