** Description changed:
+ == SRU Justification ==
+ Commit d65d87a07476 ("ext4: improve explanation of a mount failure
+ caused by a misconfigured kernel") applied to our Bionic tree via the
+ stable-update process does not consider the situation when quota support
+ was configured as a module.
+
+ This will cause failure to quotactl04 test from ubuntu_ltp_syscalls:
+ <<<test_start>>>
+ tag=quotactl04 stime=1585032076
+ cmdline="quotactl04"
+ contacts=""
+ analysis=exit
+ <<<test_output>>>
+ incrementing stop
+ tst_kconfig.c:62: INFO: Parsing kernel config
'/boot/config-4.15.0-92-generic'
+ tst_device.c:244: INFO: Using test device LTP_DEV='/dev/loop0'
+ tst_test.c:1229: INFO: Timeout per run is 0h 05m 00s
+ tst_mkfs.c:90: INFO: Formatting /dev/loop0 with ext4 opts='' extra opts='-O
quota,project'
+ mke2fs 1.44.1 (24-Mar-2018)
+ safe_macros.c:769: BROK: quotactl04.c:109: mount(/dev/loop0, mntpoint,
ext4, 0, 0x55edd2c1ab1d) failed: EINVAL (22)
+
+ Summary:
+ passed 0
+ failed 0
+ skipped 0
+ warnings 0
+ <<<execution_status>>>
+ initiation_status="ok"
+ duration=2 termination_type=exited termination_id=2 corefile=no
+ cutime=0 cstime=2
+ <<<test_end>>>
+
+ And from the syslog you will see:
+ LTP: starting quotactl04
+ EXT4-fs (loop0): The kernel was not built with CONFIG_QUOTA and
CONFIG_QFMT_V2
+
+ == Fix ==
+ * 9db176bceb5c ("ext4: fix mount failure with quota configured as module")
+
+ This patch can be cherry-picked into Bionic and it's already in Focal.
+
+ I didn't see commit d65d87a07476 in Eoan / Disco, so I think they don't
+ need this patch.
+
+ == Test ==
+ Test kernel could be found here:
+ https://people.canonical.com/~phlin/kernel/lp-1868665-quota-module/
+
+ Tested with the quotactl04 test from ubuntu_ltp_syscalls and it has
+ passed as expected.
+
+ == Regression Potential ==
+ Low, this patch is specific to ext4 quota support. And it's just using
+ a more general way to do the check.
+
+
+ == Original Bug Report ==
