We didn't use 4.19.79. We never saw this message with 4.19.78 or ealier. After the first time this happened we saw a filesystem corruption. Setup: The drbd fastexport consists of three volumes 1, 2 and 3 Each volume is backed by a logical volume drbd_fastexport01 drbd_fastexport02 drbd_fastexport03 of an LVM volumegroup drbddisks_fast This logical volumes are each on there own physical devices (which are raid1). These raid1 are based on SSDs attached to an mpt3sas driven controller. (both sides are setup like that). Regards, -- Wolfgang Walter Studentenwerk München Anstalt des öffentlichen Rechts

[PATCH v2] net: ethernet: octeon_mgmt: Account for second possible VLAN header

by Sverdlin, Alexander (Nokia - DE/Ulm)

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> Octeon's input ring-buffer entry has 14 bits-wide size field, so to account for second possible VLAN header max_mtu must be further reduced. Fixes: 109cc16526c6d ("ethernet/cavium: use core min/max MTU checking") Cc: stable(a)vger.kernel.org Signed-off-by: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> --- Changelog: v2: Added "Fixes:" tag, Cc'ed stable drivers/net/ethernet/cavium/octeon/octeon_mgmt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/cavium/octeon/octeon_mgmt.c b/drivers/net/ethernet/cavium/octeon/octeon_mgmt.c index 0e5de88..cdd7e5d 100644 --- a/drivers/net/ethernet/cavium/octeon/octeon_mgmt.c +++ b/drivers/net/ethernet/cavium/octeon/octeon_mgmt.c @@ -1499,7 +1499,7 @@ static int octeon_mgmt_probe(struct platform_device *pdev) netdev->ethtool_ops = &octeon_mgmt_ethtool_ops; netdev->min_mtu = 64 - OCTEON_MGMT_RX_HEADROOM; - netdev->max_mtu = 16383 - OCTEON_MGMT_RX_HEADROOM; + netdev->max_mtu = 16383 - OCTEON_MGMT_RX_HEADROOM - VLAN_HLEN; mac = of_get_mac_address(pdev->dev.of_node); -- 2.4.6

[PATCH v3 06/12] omap: pdata-quirks: remove openpandora quirks for mmc3 and wl1251

by H. Nikolaus Schaller

With a wl1251 child node of mmc3 in the device tree decoded in omap_hsmmc.c to handle special wl1251 initialization, we do no longer need to instantiate the mmc3 through pdata quirks. We also can remove the wlan regulator and reset/interrupt definitions and do them through device tree.

[PATCH v3 03/12] ARM: dts: pandora-common: define wl1251 as child node of mmc3

by H. Nikolaus Schaller

Since v4.7 the dma initialization requires that there is a device tree property for "rx" and "tx" channels which is not provided by the pdata-quirks initialization. By conversion of the mmc3 setup to device tree this will finally allows to remove the OpenPandora wlan specific omap3 data-quirks.

[PATCH 4.14 0/2] backport iio: stm32-adc: fix a race with dma and irq

by Fabrice Gasnier

This is a backport of "iio: stm32-adc: fix a race with dma and irq" series on top of v4.14.148 at the time of writing. The original series doesn't apply cleanly on v4.14.x: the precursor patch needed a slight update. Original series can be found in [1]. [1] https://www.lkml.org/lkml/2019/9/17/394 Original cover-letter: This series fixes a race condition observed when using several ADCs with DMA and irq. There's a precusor patch to the fix. It keeps registers definitions as a whole block, to ease readability and allow simple (readl) access path to EOC bits in stm32-adc-core driver.
