H A D | fs.h | diff 68568 Fri Nov 10 12:54:15 MST 2000 bde 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.
