In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix use-after-free on inode when scanning root during em shrinking
At btrfs_scan_root() we are accessing the inode's root (and fs_info) in a
call to btrfs_fs_closing() after we have scheduled the inode for a delayed
iput, and that can result in a use-after-free on the inode in case the
cleaner kthread does the iput before we dereference the inode in the call
to btrfs_fs_closing().
Fix this by using the fs_info stored already in a local variable instead
of doing inode->root->fs_info.
