Boaz Harrosh c999ff6802 pnfs-obj: Fix __r4w_get_page when offset is beyond i_size ... It is very common for the end of the file to be unaligned on stripe size. But since we know it's beyond file's end then the XOR should be preformed with all zeros. Old code used to just read zeros out of the OSD devices, which is a great waist. But what scares me more about this situation is that, we now have pages attached to the file's mapping that are beyond i_size. I don't like the kind of bugs this calls for. Fix both birds, by returning a global zero_page, if offset is beyond i_size. TODO: Change the API to ->__r4w_get_page() so a NULL can be returned without being considered as error, since XOR API treats NULL entries as zero_pages. [Bug since 3.2. Should apply the same way to all Kernels since] CC: Stable Tree <stable@kernel.org> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>		2012-07-20 11:50:31 +03:00
