PATCH 1/5 fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr()

From: Konstantin Komarov <[email protected]>

[ Upstream commit 2afd4d267e6dbaec8d3ccd4f5396cb84bc67aa2e ]

Extended the mi_enum_attr() function interface with an additional parameter, struct ntfs_inode *ni, to allow marking the inode as bad as soon as an error is detected.

PATCH 3/5 Grab mm lock before grabbing pt lock

In reply to Sasha Levin

From: Maksym Planeta <[email protected]>

[ Upstream commit 6d002348789bc16e9203e9818b7a3688787e3b29 ]

Function xen_pin_page calls xen_pte_lock, which in turn grab page table lock (ptlock). When locking, xen_pte_lock expect mm->page_table_lock to be held before grabbing ptlock, but this does not happen when pinning is caused by xen_mm_pin_all.

This commit addresses lockdep warning below, which shows up when suspending a Xen VM.

PATCH 4/5 selftests: gpio: gpio-sim: Fix missing chip disablements

In reply to Sasha Levin

From: Koichiro Den <[email protected]>

[ Upstream commit f8524ac33cd452aef5384504b3264db6039a455e ]

Since upstream commit 8bd76b3d3f3a ("gpio: sim: lock up configfs that an instantiated device depends on"), rmdir for an active virtual devices been prohibited.

Update gpio-sim selftest to align with the change.

PATCH 5/5 ACPI: x86: Add skip i2c clients quirk for Vexia EDU ATLA 10 tablet 5V

In reply to Sasha Levin

From: Hans de Goede <[email protected]>

[ Upstream commit 8f62ca9c338aae4f73e9ce0221c3d4668359ddd8 ]

The Vexia EDU ATLA 10 tablet comes in 2 different versions with significantly different mainboards. The only outward difference is that the charging barrel on one is marked 5V and the other is marked 9V.

Both ship with Android 4.4 as factory OS and have the usual broken DSDT issues for x86 Android tablets.

Add a quirk to skip ACPI I2C client enumeration for the 5V version to complement the existing quirk for the 9V version.
