dillon 2001/01/29 22:31:59 PST Modified files: sys/ufs/ffs ffs_softdep.c Log: Fix a race between the syncer and umount. When you umount a softupdates filesystem softdep_process_worklist() is called in a loop until it indicates that no dependancies remain, but the determination of that fact depends on there only being one softdep_process_worklist() instance running. It was possible for the syncer to also be running softdep_process_worklist() and the pre-existing checks in the code to prevent this were not sufficient to prevent the race. This patch solves the problem.
