; Patch for MountVol
|
|
;
|
|
; Patched using ExtFSHook.
|
|
;
|
|
; The MountVol patch fixes a problem in the recognition of already mounted, but offline, volumes:
|
|
; the recognition loop stops checking VCBs when the first one matching name and creation date is
|
|
; found. If the LEOF check subsequently fails, no other VCBs are even considered.
|
|
;
|
|
; We check for this condition and jump back into the File System to fix it, or we jump on
|
|
; down the ExtFSHook chain.

; Patch for MFS Rename
|
|
;
|
|
; Patched using ExtFSHook.
|
|
;
|
|
; The rename patch fixes a problem encountered when renaming MFS volumes: D0 used to index the length
|
|
; of the new name, and isn't cleared on exit, which prompts CmdDone to generate a TFS internal error code
|
|
; message in D0's place.

;

; We check for this condition, fix it and jump on down the ExtFSHook chain.

; name, which leaves D0 with the length of the new name. Rename fails to clear D0 on its subsequent
|
|
; (successful) exit, and so leaves D0 with some small, positive, integer at CmdDone. CmdDone considers
|
|
; D0 an internal error message code, and promptly converts it to an FSDSIntErr code (-127). At the
