Subject[PATCH 1/6] vfs: Fix vfs_dup_fs_context()
From
Date
vfs_dup_fs_context() allocates the wrong type of structure and as a result
ends up with one that's too small.

This isn't a problem at this time as nothing uses vfs_dup_fs_context() yet
(until nfs and btrfs conversions come along).

Fixes: ad3e21240b41 ("vfs: Implement a filesystem superblock creation/configuration context")
