Description of problem:
The patch SHA-1: d50f22e discripted that "performance/io-cache: update pages with write data” . How after that patch commit and disable md-cache sometimes that gcc compilation file can not execute right now.

Version-Release number of selected component (if applicable):
gluster version 6, io-cache

Steps to Reproduce:
1.gluster v create testvol_distributed host1:/bricks/brick1/testvol_distributed_brick0 host2:/bricks/brick1/testvol_distributed_brick0 host3:/bricks/brick1/testvol_distributed_brick0
2.gluster v set testvol_distributed performance.md-cache-pass-through true
3.gluster v start testvol_distributed
4.mount -t glusterfs 127.0.0.1:/testvol_distributed /mnt/testvol_dispersed
5.gcc stat.c -o stat1 -lm ; ./stat1 smcomp.time
-bash: ./stat1: cannot execute binary file
6.we should execute stat1 right now. we maybe not reproduce this problem so

Actual results:
can execute binary file

Expected results:
can execute binary file

Additional info:
The reason is not do ioc_inode_flush or update io cache page failed after ioc_writev_cbk. The patch commit ioc_inode_flush used by steps mdc_inode_iatt_set_validate->inode_invalidate->ioc_invalidate->ioc_inode_flush .
