2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Boaz Harrosh <[email protected]> commit 0b0abeaf3d30cec03ac6497fe978b8f7edecc5ae upstream. This reverts commit 115e19c53501edc11f730191f7f047736815ae3d. Apparently setting inode->bdi to one's own sb->s_bdi stops VFS from sending *read-aheads*. This problem was bisected to this commit. A revert fixes it. I'll investigate farther why is this happening for the next Kernel, but for now a revert. I'm sending to [email protected] as well, since it exists also in 2.6.37. 2.6.36 is good and does not have this patch.
