[PATCH] freevxfs: Add missing lock_kernel() to vxfs_readdir
Commit 7b2fd697427e73c81d5fa659efd91bd07d303b0e in the historical GIT tree stopped calling the readdir member of a file_operations struct with the big kernel lock held, and fixed up all the readdir functions to do their own locking. However, that change added calls to unlock_kernel() in vxfs_readdir, but no call to lock_kernel(). Fix this by adding a call to lock_kernel().
