Utah directory being written to blocks parent directory listing.

[Reisen]

I have mounted utahfs in my home directory, under $HOME/Utah to experiment with. When copying a large file in, the parent directory becomes blocked from listing. Attempting to Ctrl+C ls does work, but takes a long time.

Steps to reproduce

~$ # Terminal 1
~$ utahfs-client -conf ~/utahfs.yaml -mnt ~/Utah
~$ cp largefile Utah/largefile

~$ # Terminal 2
~$ ls
<blocked>

Eventually the operation can be killed, the following log is printed:

2020/06/23 12:00:02 filesystem.go:661: context canceled
fuse: 2020/06/23 12:00:02 connection.go:486: *fuseops.GetInodeAttributesOp error: app: transaction not active

This sounds like it might be caused by mutex starvation. Which version of Go are you using?

[Reisen]

$ go version
go version go1.14.4 linux/amd64

I installed utah via go get.
