Modified files:
sys/vm vm_object.c vm_object.h vnode_pager.c
sys/ufs/ufs ufs_lookup.c
Log:
Allow VM object creation in ufs_lookup. (If vfs.vmiodirenable is set)
Directory IO without a VM object will store data in 'malloced' buffers
severely limiting caching of the data. Without this change VM objects for
directories are only created on an open() of the directory.
TODO: Inline test if VM object already exists to avoid locking/function call
overhead.
