Hello Hirofumi,
I would like to export this symbol from the vfat code and add this patch
to the Linux kernel. You are listed as the MAINTAINER for FAT and VFAT.
As such, I need your approval to do it.
The reason that I need to export this symbol is to allow for file based
DMA in which the file needs to be pre-allocated. The pre-allocated block
addresses are passed to a DMA engine which then directly transfers the
data to non-volatile storage.
Please let me know if you have any objections to exporting this symbol
or if you need additional information from me concerning this change
request. I am happy to answer any questions that you may have about this
in the meantime.
Thanks,
David Cross
