inode deadlock: can't reclaim VLRU: suggestions please [was RE: k ernel deadlock]
...ue
- can acquire v_interlock
However, few nodes meet these constraints either.
Which of the following approaches seem best:
1. Can I do away with some of the VMIGHTFREE() criteria?
I.e., are they constraints or merely heuristics?
#define VMIGHTFREE(vp) \
(!((vp)->v_flag & (VFREE|VDOOMED|VXLOCK)) && \
LIST_EMPTY(&(vp)->v_cache_src) && !(vp)->v_usecount)
2. If there is a dependancy on one of the user processes,
can I determine the offendor (maybe kill it)?
3. Should vnlru process signal the requestor if as few as one
nodes have been reclaim...
