This is a note to let you know that I have just added a patch titled btrfs: don't stop searching after encountering the wrong item to the linux-3.5.y-queue branch of the 3.5.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-3.5.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 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 0ca528eda4b4744875ea4f039744920755e4a3a7 Mon Sep 17 00:00:00 2001 From: Gabriel de Perthuis <g2p.code@gmail.com> Date: Mon, 6 May 2013 17:40:18 +0000 Subject: [PATCH] btrfs: don't stop searching after encountering the wrong item commit 03b71c6ca6286625d8f1ed44aabab9b5bf5dac10 upstream. The search ioctl skips items that are too large for a result buffer, but inline items of a certain size occuring before any search result is found would trigger an overflow and stop the search entirely.
