3.11.10.14 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Liu Bo <[email protected]> commit 5dca6eea91653e9949ce6eb9e9acab6277e2f2c4 upstream. According to commit 865ffef3797da2cac85b3354b5b6050dc9660978 (fs: fix fsync() error reporting), it's not stable to just check error pages because pages can be truncated or invalidated, we should also mark mapping with error flag so that a later fsync can catch the error.
