Subject: [PATCH 3.18 24/29] ubifs: Fix synced_i_size calculation for xattr inodes
Date: Fri, 7 Sep 2018 23:10:45 +0200 [thread overview]
Message-ID: <20180907210911.141394003@linuxfoundation.org> (raw)
In-Reply-To: <20180907210909.523240901@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Weinberger <richard@nod.at>
commit 59965593205fa4044850d35ee3557cf0b7edcd14 upstream.
In ubifs_jnl_update() we sync parent and child inodes to the flash,
in case of xattrs, the parent inode (AKA host inode) has a non-zero
data_len. Therefore we need to adjust synced_i_size too.
This issue was reported by ubifs self tests unter a xattr related work
load.
UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: ui_size is 4, synced_i_size is 0, but inode is clean
UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: i_ino 65, i_mode 0x81a4, i_size 4
