MFC rev. 1.147

2007-09-24T13:39:06Z

Fix a DIV0 in case a large value for fs_avgfilesize or fs_avgfpdir is given (with newfs or tunefs) and dirsize overflows. In case dirsize is <= 0 because of an overflow set maxcontigdirs to 0 so it will be 1 later. This is what would happen for large fs_avgfilesize. [1] Submitted by: pjd [1]

Add new BOP, bop_bdwrite(), to do dirty buffer flushing for same vnode in the bdwrite(). Default implementation, bufbdflush(), refactors the code from bdwrite(). For ffs device buffers, specialized implementation is used. This commit changes KPI/KBI, thus recompilation of out of tree kernel modules is required. Approved by: re (kensmith)

When LK_NOWAIT is passed as argument to process_worklist_item(), this does not prevent handle_workitem_remove() from recursing into a blocking version. Add the dirrem to worklist instead of processing it now if this is the case.
