This is a note to let you know that I have just added a patch titled Btrfs: mark mapping with error flag to report errors to userspace to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From afc8e4fba81d3df9dacc15ef6d8758ab9eae7d4d Mon Sep 17 00:00:00 2001 From: Liu Bo <bo.li.liu@oracle.com> Date: Mon, 12 May 2014 12:47:36 +0800 Subject: Btrfs: mark mapping with error flag to report errors to userspace 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.
