Hi ,
take the following steps:
$mount -t ceph monip:6789:/ /mnt/ceph
$dd if=/dev/zero of=/mnt/ceph/2G bs=1M count=2048 conv=fsync
copy_test:
#!/bin/bash
cp /mnt/ceph/2G /mnt/$1/
--
$copy_test 01 &
$copy_test 02 &
$copy_test 03 &
$copy_test 04 &
$copy_test 05 &
$c
Thanks, Jeff!
Was there a workload that reliably triggered this case?

Hi ,
start_read() do twice "kfree(pages)",
out_pages:
ceph_release_page_vector(pages, nr_pages);
kfree(pages);
ceph_release_page_vector had kfree pages, continue to do kfree(pages),
sometimes ,async read ,printk "BUG kmalloc-16: Object already
free" ,then OOPS.

Er, not really.. this'll go upstream during the next merge window, along
with the readahead code. :)

Can I add your Signed-off-by: on that?
I'll send this upstream with the other patches so it'll hopefully make
3.1...
Thanks!

The finish_read callback introduced in 63c90314546c1cec1f220f6ab24ea
fails to release the page list allocated in start_read.
