Modified files:
sys/gnu/ext2fs fs.h
Log:
Quick fix for not writing group descriptor group, inode bitmaps or
block bitmaps before unmount() completes. They were written using
bdwrite(), so they were normally written less than 32 seconds after
unmount(), but this is too late if the media is removed or the system
is rebooted soon after unmount(). sync()ing before unmount() didn't
help, because ext2fs uses buggy private caching for these blocks --
it doesn't even bdwrite() them until they are uncached or the filesystem
is unmounted. sync()ing after unmount() didn't help, because sync()
only applies to (vnodes for) mounted filesystems.
