KernReadFileAtCache
From EDM2
This seems to do the same as KernReadAtFile, but reads from the cache and returns the corresponding pages of the cache data structure.
Synopsis
APIRET APIENTRY KernReadFileAtCache(KEEhfile khfd,KEECachePages** ptr, QWORD off, ULONG nbytes, PULONG nread);
Parameters

Comments
Yet another JFS hack. Meanwhile I understand why IBM is reluctant to provide JFS support for Warp 4.
