btrfs: annotate device name rcu_string with __rcu
This patch fixes the following sparse errors in
fs/btrfs/super.c in function btrfs_show_devname()
fs/btrfs/super.c: error: incompatible types in comparison expression (different address spaces):
fs/btrfs/super.c: struct rcu_string [noderef] <asn:4> *
fs/btrfs/super.c: struct rcu_string *
The error was because of the following line in function btrfs_show_devname():
if (first_dev)
seq_escape(m, rcu_str_deref(first_dev->name), " \t\n\\");
Annotating the btrfs_device::name member with __rcu fixes the sparse
error.
