[reactos] 07/10: [NTOS:IO] Refactoring of the driver initialization code (2)

by Victor Perevertkin

https://git.reactos.org/?p=reactos.git;a=commitdiff;h=4c95339da0addaa59a0d5… commit 4c95339da0addaa59a0d584c240a34f708079ce5 Author: Victor Perevertkin <victor.perevertkin(a)reactos.org> AuthorDate: Wed Nov 25 03:18:31 2020 +0300 Commit: Victor Perevertkin <victor.perevertkin(a)reactos.org> CommitDate: Mon Jan 4 16:50:33 2021 +0300 [NTOS:IO] Refactoring of the driver initialization code (2) - Do not hold the IopDriverLoadResource while trying to reference a driver object (but still acquire it when we actually need to load a driver) - Change IopLoadDriver and IopInitializeDriverModule to use registry handle instead of a service name string and/or full registry path - Do not try to reference a driver object inside IopLoadDriver.
