svn commit: r289279 - in head/sys: kern vm

[Adrian Chadd]

Hi Tijl, and others;

Here's something that Jeff came up with that fixes my problem:

adrian at victoria:~/work/freebsd/head-embedded/src % svn diff sys/kern/
Index: sys/kern/vfs_bio.c

        } while(buf_scan(false) == 0);

        if (reserved)
-               bufspace_release(maxsize);
+               atomic_subtract_long(&bufspace, maxsize);
        if (bp != NULL) {
                bp->b_flags |= B_INVAL;
                brelse(bp);


Would you/others please try this and see if it improves things? It
improves things for me on these memory-starved MIPS boards.
