of the D_NEWBLK kinds of dependencies (i.e. D_ALLOCDIRECT and D_ALLOCINDIR), which can exhaust kmem. Handle excess of D_NEWBLK in the same way as excess of D_INODEDEP and D_DIRREM, by scheduling ast to flush dependencies, after the thread, which created new dep, left the VFS/FFS innards. For D_NEWBLK, the only way to get rid of them is to do full sync, since items are attached to data blocks of arbitrary vnodes. The check for D_NEWBLK excess in softdep_ast_cleanup_proc() is unlocked. For 32bit arches, reduce the total amount of allowed dependencies by two. It could be considered increasing the limit for 64 bit platforms with direct maps.
