Hi Miao,
Your updated V4 patch no longer gives me a hang. Thank you.
In the latest V4, btrfs_remove_delayed_node() does just release
a delayed node and returns for most of the time, but for space
cache inodes, it takes trans_mutex and writes the delayed nodes
out to the tree. Is my understanding
Hi Chris,
I have been using that option.

I think there
Hi Miao,
The V4 still hangs. Does the new function, btrfs_update_inode_nodelayed() you
introduced to the V4
need take care of a delayed node (commit delayed items of the inode and set the
delayed note to NULL)?
Below is my experimental patch on top of V4 trying to avoid taking trans_mutex

Thank you both for your help. I agree that we need to reserve 5 items for that
operation.

Hi,
I did some testing, the speedup results match yours. I was watching kmem cache
stats of the delayed_node, seem to behave well. Increase and decrease of
number of active objects, from 3 to about ~400 (creat_unlink 5) and went
back to initial values after a few seconds. On my setup, there ar

Miao's patch (http://marc.in
Hi Miao,
The V3 patch on top of the next-rc fails to pass an xfstests test 13.
In the btrfs link path, we need to reserve one more metadata in the
trans_block_rsv for the delayed inode update (if needed) to complete.
Here's the log from the test:
