New Revision: 24552
URL: http://svn.reactos.org/svn/reactos?rev=24552&view=rev
Log:
- Merge some parts of IoInitSystem in the same main function instead of calling out to 10
external modules.
- Re-factor some code into smaller functions.
- Don't create some Object Directories twice, since now ExpCreateSystemRootLink does
some of them.
- Add some failure paths to I/O Init.
- Implement a function to mark the boot partition DO_SYSTEM_BOOT_PARTITION in order to
better catch some bugchecks.
