Re: [PATCH v2] btrfs: explicitly set control file's private_data

[Tom Van Braeckel]

Err, upon further inspection, I think that this was a false positive.

Btrfs relies on the initial value of the private_data member of a file
being NULL in the regular ioctl operation handler for
BTRFS_IOC_TRANS_START but it does not use the miscdevice framework for
those files.

It *does* use the miscdevice framework in the ioctl operation handler
of the /dev/btrfs-control file but there it does not use the file's
private_data member. So IMHO, the proposed patch is not necessary...
