Only change from previous post is explicitly checking md_map for NULL before hash_free and lookup.

These patches are rebased on top of current master. In addition, I've made the following changes: * Fixed whitespace error. * Functions return -1 on error. * Added a debug message when guest contains md devices, but nothing was parsed from mdadm.conf.

This patch fixes inspection when fstab contains devices md devices specified as /dev/mdN. The appliance creates these devices without reference to the guest's mdadm.conf so, for e.g. /dev/md0 in the guest will often be created as /dev/md127 in the appliance. With this patch, we match the uuids of detected md devices against uuids specified in mdadm.conf, and map them appropriately when we

Hi, I recently came across a situation where "rsync --inplace" performs very poorly. If both the source and destination files contain long sequences of identical blocks, but not necessarily in the same location, the sender can spend an inordinate amount of CPU time finding matching blocks. In my case, I came across this problem while backing up multi-hundred-gigabyte MySQL database

This patch series changes a small part of the library to use __attribute__((cleanup(...))) to automatically free memory when pointers go out of the current scope. In general terms this seems to be a small win although you do have to use it carefully. For functions where you can completely get rid of the "exit code paths", it can simplify things. For a good example, see the

...the code regarding paging --> spending a lot of time in mm/*.*, as well as some of the other parts up a level or two, but I''m still unclear as to some key things. Here''s what I think I know: I think I know how a domain''s shadow page table is first allocated E.G. the hash_table is xmalloc''ed and when it is destroyed E.G. xfree''ed. I believe I have identified the functions where a shadow page is inserted and deleted with all the tlb modifications that go along with that. I''m semi-comfortable with the format of the shadow page table itself. In 3...

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've
