-/* --------------------------------------------------------*
-*
-* RAID support for MySQL. Raid 0 (stiping) only implemented yet.
-*
-* Why RAID? Why it must be in MySQL?
-*
-* This is because then you can:
-* 1. Have bigger tables than your OS limit. In time of writing this
-* we are hitting to 2GB limit under linux/ext2
-* 2. You can get more speed from IO bottleneck by putting
-* Raid dirs on different physical disks.
-* 3. Getting more fault tolerance (not implemented yet)
-*
-* Why not to use RAID:
-*
-* 1. You are losing some processor power to calculate things,
-* do more syscalls and interrupts.
-*
-* Functionality is supplied by two classes: RaidFd and RaidName.
-* RaidFd supports funtionality over file descriptors like
-* open/create/write/seek/close. RaidName supports functionality
-* like rename/delete where we have no relations to filedescriptors.
-* RaidName can be prorably unchanged for different Raid levels. RaidFd
-* have to be virtual I think ;).
-* You can speed up some calls in MySQL code by skipping RAID code.
-* For example LOAD DATA INFILE never needs to read RAID-ed files.
-* This can be done adding proper "#undef my_read" or similar undef-s
-* in your code. Check out the raid.h!
-*
-* Some explanation about _seek_vector[]
-* This is seek cache. RAID seeks too much and we cacheing this. We
-* fool it and just storing new position in file to _seek_vector.
-* When there is no seeks to do, we are putting RAID_SEEK_DONE into it.
-* Any other value requires seeking to that position.
-*
-* TODO:
-*
-*
-* - Implement other fancy things like RAID 1 (mirroring) and RAID 5.
-* Should not to be very complex.
-*
-* - Optimize big blob writes by resorting write buffers and writing
-* big chunks at once instead of doing many syscalls. - after thinking I
-* found this is useless. This is because same thing one can do with just
-* increasing RAID_CHUNKSIZE. Monty, what do you think? tonu.
-*
-* - If needed, then implement missing syscalls. One known to miss is stat();
-*
-* - Make and use a thread safe dynamic_array buffer. The used one
-* will not work if needs to be extended at the same time someone is
-* accessing it.
