[PATCH 5/7] tests: Modify f_large_dir test to excercise indexed dir handling

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

 



Modify f_large_dir test to create indexed directory and create entries
in it. That way the new code in ext2fs_link() for addition of entries
into indexed directories gets executed including various special cases
when growing htree.
