| H A D | extents.c | 03e916fa Sun Jan 08 20:00:35 CST 2017 Roman Pen <roman.penyaev@profitbricks.com> ext4: do not polute the extents cache while shifting extents
Inside ext4_ext_shift_extents() function ext4_find_extent() is called
without EXT4_EX_NOCACHE flag, which should prevent cache population.
This leads to oudated offsets in the extents tree and wrong blocks
afterwards.
Patch fixes the problem providing EXT4_EX_NOCACHE flag for each
ext4_find_extents() call inside ext4_ext_shift_extents function.
