My apologies for annoying everyone with the d_alloc messages. They are
serving a purpose though -- I'm trying to find a good way to keep
negative dentries under control. If we get a sudden flood of negative
dentries, this can make it inefficient to search the dentry list for
freeable inodes or pages.
For example, doing a rm -rf linux-2.1.56 will create several thousand
negative dentries on the unused list. The d_alloc pruning helps keep
some semblance of balance in the dentry list, but I hadn't intended for
this code to be used frequently. My newer dcache code prunes negative
dentries more aggressively and so seldom triggers the d_alloc message.
Regards,
Bill
