Andreas GruenbacherandSasha Levin 5d5d9ec957 gfs2: fiemap page fault fix ...

[ Upstream commit e411d74cc5 ]

In gfs2_fiemap(), we are calling iomap_fiemap() while holding the inode
glock.  This can lead to recursive glock taking if the fiemap buffer is
memory mapped to the same inode and accessing it triggers a page fault.

Fix by disabling page faults for iomap_fiemap() and faulting in the
buffer by hand if necessary.

Fixes xfstest generic/742.
