Hi,

I'm seeing a regression with Linux next with commit 7b6ec2ae877a
("fs: convert return type int to vm_fault_t") where apps can just
hang.

The reproducable test case I have is to remove a distro package
and then add it back where adding the package back just hangs and
the package file seems corrupted.

This is with ext4 rootfs on MMC, NFSroot does not have this
issue. Any ideas?

Regards,

Tony

This is a bad commit and there is a plan to remove it from all the tree.
Not sure why it is still showing in linux-next tree.

OK, I have removed that commit (and the following fix patch) from
linux-next today (in case Andrew doesn't get around to it).
