Subject: Revert "exofs: Set i_mapping->backing_dev_info anyway"
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.
