ext4 ignoring rootfs default mount options

While switching a system from using ext3 to ext4 (It's about time) I discovered that setting default options for the filesystem using tune2fs -o doesn't work for the root filesystem when mounted by the kernel itself. Filesystems mounted from userspace with the mount command use the options set

[PATCH v8] PCI: Workaround wrong flags completions for IDT switch

The IDT switch incorrectly flags an ACS source violation on a read config request to an end point device on the completion (IDT 89H32H8G3-YC, errata #36) even though the PCI Express spec states that completions are never affected by ACS source violation (PCI Spec 3.1, Section 6.12.1.1). Here's

[PATCH v8 52/63] memfd: Convert shmem_tag_pins to XArray

From: Matthew Wilcox Simplify the locking by taking the spinlock while we walk the tree on the assumption that many acquires and releases of the lock will be worse than holding the lock for a (potentially) long time. We could replicate the same locking behaviour with the

[PATCH v8 50/63] shmem: Convert shmem_free_swap to XArray

From: Matthew Wilcox This is a perfect use for xa_cmpxchg(). Note the use of 0 for GFP flags; we won't be allocating memory. Signed-off-by: Matthew Wilcox --- mm/shmem.c | 7 ++- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git

[PATCH v8 51/63] shmem: Convert shmem_partial_swap_usage to XArray

[PATCH v8 49/63] shmem: Convert shmem_alloc_hugepage to XArray

From: Matthew Wilcox xa_find() is a slightly easier API to use than radix_tree_gang_lookup_slot() because it contains its own RCU locking. Signed-off-by: Matthew Wilcox --- mm/shmem.c | 14 -- 1 file changed, 4 insertions(+), 10

[PATCH v8 23/63] xarray: Add xas_next and xas_prev

From: Matthew Wilcox These two functions move the xas index by one position, and adjust the rest of the iterator state to match it. This is more efficient than calling xas_set() as it keeps the iterator at the leaves of the tree instead of walking the iterator from the

[PATCH v8 03/63] arm64: Turn flush_dcache_mmap_lock into a no-op

[RESEND PATCH v3] crypto: add zBeWalgo compression for zram

Currently ZRAM uses compression-algorithms from the crypto-api. ZRAM compresses each page individually. As a result the compression algorithm is forced to use a very small sliding window. None of the available compression algorithms is designed to achieve high compression ratios with small inputs.

When we hot-remove the device, we first receive a PCI_EJECT message and then receive a PCI_BUS_RELATIONS message with bus_rel->device_count == 0. The first message is offloaded to hv_eject_device_work(), and the second is offloaded to pci_devices_present_work(). Both the paths can be running
