Modified Files:
src/sys/fs/tmpfs: tmpfs_vnops.c
Log Message:
Disable use of UBC_FAULTBUSY in tmpfs_write() for now,
which brings back zeroing of all new tmpfs data pages.
The existing code that enables this optimization skips the zeroing
in numerous cases where it is needed, resulting in corrupted files
and data leaks from the page's previous identity.
