Description Vijay Bellur 2009-07-30 07:17:52 UTC

Running dbench -s 42 leads to incorrect statistics for number of open files in Posix. Have seen this leading to negative values many times.

stats.nr_files = -2 is what I observed in a server after running dbench -s 42 in a setup involving distribute over two nodes.

private is being updated in posix without holding any locks. Hence the bug. This needs to be fixed wherever private is being updated in posix xlator.
