Ceph » Linux kernel client

Ran against a vstart ceph cluster based the latest upstream code, then mount the kclient, by running the following test script serveral times:

# for i in {1..10000}; do echo $i > file$i.txt; done; for i in {1..10000}; do rm -f file$i.txt; done;

It will be stuck and I can see the following dmesg logs:
