->writepage is a very inefficient method to write back data, and only used through write_cache_pages or as a fallback when no ->migrate_folio method is present. Set ->migrate_folio to the generic buffer_head based helper, and remove the ->writepage implementation in extfat. Signed-off-by:

We do not need to writeout modified directory blocks immediately when modifying them while the page is locked. It is enough to do the flush somewhat later which has the added benefit that inode times can be flushed as well. It also allows us to stop depending on write_one_page() function. Signed-off-by:

However, brelse() is called by udf_rename(), too. So, b_count on buffer_head becomes unbalanced. This patch fixes the issue by not calling brelse() by udf_rename() when udf_find_entry() returns NULL.

This reverts commit 72a95859. It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances, which use the syscon driver. Little-endian is not effected, which means likely it's important to handle regmap_get_val_endian() in this function after all. Fixes: 72a95859 ("mfd: syscon: Remove repetition of the regmap_get_val_endian()") Reviewed-by:

Commit bfca3dd3 ("kernel/utsname_sysctl.c: print kernel arch") added a new entry to the uts_kern_table[] array, but didn't update the UTS_PROC_xyz enumerators of older entries, breaking anything that used them. Which is admittedly not many cases: it's really just the two uses of uts_proc_notify() in kernel/sys.c. But apparently journald-systemd actually uses this to detect hostname changes. Reported-by:

The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in struct which means it has a different struct size depending on whether it gets called from 32bit or 64bit code. This patch introduces compat code that converts from the 32bit struct to its 64bit counterpart which then gets used going forward internally. With this applied, 32bit QEMU can successfully set MSR bitmaps when running on 64bit kernels. Reported-by:

When an extended state component is not present in fpstate, but in init state, the function copies from init_fpstate via copy_feature(). But, dynamic states are not present in init_fpstate because of all-zeros init states. Then retrieving them from init_fpstate will explode like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... RIP: 0010:memcpy_erms+0x6/0x10 ? __copy_xstate_to_uabi_buf+0x381/0x870 fpu_copy_guest_fpstate_to_uabi+0x28/0x80 kvm_arch_vcpu_ioctl+0x14c/0x1460 [kvm] ? __this_cpu_preempt_check+0x13/0x20 ? vmx_vcpu_put+0x2e/0x260 [kvm_intel] kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? __fget_light+0xd4/0x130 __x64_sys_ioctl+0xe3/0x910 ? debug_smp_processor_id+0x17/0x20 ? fpregs_assert_state_consistent+0x27/0x50 do_syscall_64+0x3f/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd Adjust the 'mask' to zero out the userspace buffer for the features that are not available both from fpstate and from init_fpstate. The dynamic features depend on the compacted XSAVE format. Ensure it is enabled before reading XCOMP_BV in init_fpstate.
