KernReadFileAtCache

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

 * khfd :    SFT pointer
 * ptr :    Pointer to a variable the receives the cache data structure for the specified data blocks.
 * off :    Offset in file to start reading
 * nbytes :    Number of bytes to read
 * nread :    Pointer to an ULONG to receive the number of bytes actually read.

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