Goldwyn RodriguesandGreg Kroah-Hartman 520e8b4bcf btrfs: tracepoints: get correct superblock from dentry in event btrfs_sync_file() ...

[ Upstream commit a85b46db14 ]

If overlay is used on top of btrfs, dentry->d_sb translates to overlay's
super block and fsid assignment will lead to a crash.

Use file_inode(file)->i_sb to always get btrfs_sb.
