[PATCH 0/5] Btrfs: mount error handling fixes
...es (memory leaks, NULL pointer dereferences and devices
hanging in busy state) to sanitize error handling during mount sequence.
This is on top of for-linus + slyfox''s double-free fix.

give me some works
hello, Chris
In the next several months, I will have a lot of spare time. I will
be happy if you assign some work to me. I have learn linux kernel
for years but only fix a few small bugs in IP stack. In the past few
months, I read some EXT4/VFS codes. I began reading source of btrfs
ten days ago and have read it twice now.
Regards

"Input/output error" on mkdir for PPC64 based client
Looks like it is an issue with architecture compatibility in RPC layer (ie,
with XDRs and how it is used). Just glance the logs of the client process
where you saw the errors, which could give some hints. If you don't
understand the logs, share them, so we will try to look into it.

"Input/output error" on mkdir for PPC64 based client
I recently compiled the 3.10-5 client from source on a few PPC64 systems
running RHEL 7.3. They are mounting a Gluster volume which is hosted on
more traditional x86 servers.
Everything seems to be working properly except for creating new
directories from the PPC64 clients. The mkdir command gives a
"Input/output error" and for the first few minutes the new directory is
