Previously we use "unsigned long *" for those two bitmaps. But since we only support fixed stripe length (64KiB, already checked in tree-checker), "unsigned long *" is really a waste of memory, while we can just use "unsigned long". This saves us 8 bytes in total for scrub_parity. To be extra safe, add an ASSERT() making sure calclulated @nsectors is always smaller than BITS_PER_LONG.

This eliminates 2 labels and makes the code generally more streamlined. Also rename the 'out_bargs' label to 'out_unlock' since bargs is going to be freed under the 'out' label. This also fixes a memory leak since bargs wasn't correctly freed in one of the condition which are now moved in btrfs_try_lock_balance.

This function contains the factored out locking sequence of btrfs_ioctl_balance. Having this piece of code separate helps to simplify btrfs_ioctl_balance which has too complicated.

The function submit_data_read_repair() is only called for buffered data read path, thus those members can be calculated using bvec directly: - start start = page_offset(bvec->bv_page) + bvec->bv_offset; - end end = start + bvec->bv_len - 1; - page page = bvec->bv_page; - pgoff pgoff = bvec->bv_offset; Thus we can safely replace those 4 parameters with just one bio_vec. Also remove the unused return value.

Although we have several data csum verification code, we never have a function really just to verify checksum for one sector. Function check_data_csum() do extra work for error reporting, thus it requires a lot of extra things like file offset, bio_offset etc. Function btrfs_verify_data_csum() is even worse, it will utilize page checked flag, which means it can not be utilized for direct IO pages. Here we introduce a new helper, btrfs_check_sector_csum(), which really only accept a sector in page, and expected checksum pointer. We use this function to implement check_data_csum(), and export it for incoming patch.

The mitigations for RETBleed are currently ineffective on x86_32 since entry_32.S does not use the required macros. However, for an x86_32 target, the kconfig symbols for them are still enabled by default and /sys/devices/system/cpu/vulnerabilities/retbleed will wrongly report that mitigations are in place. Make all of these symbols depend on X86_64, and only enable RETHUNK by default on X86_64.

That SRCU fix for KLP introduced large (as in minutes) boot-time delays to embedded Linux kernels running on qemu/KVM. These delays were due to the emulation of certain MMIO operations controlling memory layout, which were emulated with one expedited grace period per access. Common configurations required thousands of boot-time MMIO accesses, and thus thousands of boot-time expedited SRCU grace periods. In these configurations, the occasional sleeps that allowed KLP to proceed caused excessive boot delays. These commits preserve enough sleeps to permit KLP to proceed, but few enough that the virtual embedded kernels still boot reasonably quickly. This represents a regression introduced in the v5.19 merge window, and the bug is causing significant inconvenience" * tag 'rcu-urgent.2022.07.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: srcu: Make expedited RCU grace periods block even less frequently srcu: Block less aggressively for expedited grace periods

Sudip reports that alpha doesn't build properly, with errors like include/asm-generic/tlb.h:401:1: error: redefinition of 'tlb_update_vma_flags' 401 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma) | ^~~~~~~~~~~~~~~~~~~~ include/asm-generic/tlb.h:372:1: note: previous definition of 'tlb_update_vma_flags' with type 'void(struct mmu_gather *, struct vm_area_struct *)' 372 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma) { } the cause being that We have this odd situation where some architectures were never converted to the newer TLB flushing interfaces that have a range for the flush. Instead people left them alone, and we have them select the MMU_GATHER_NO_RANGE config option to make the tlb header files account for this. Peter Zijlstra cleaned some of these nasty header file games up in commits 1e9fdf21 ("mmu_gather: Remove per arch tlb_{start,end}_vma()") 18ba064e ("mmu_gather: Let there be one tlb_{start,end}_vma() implementation") but tlb_update_vma_flags() was left alone, and then commit b67fbebd ("mmu_gather: Force tlb-flush VM_PFNMAP vmas") ended up removing only _one_ of the two stale duplicate dummy inline functions. This removes the other stale one. Somebody braver than me should try to remove MMU_GATHER_NO_RANGE entirely, but it requires fixing up the oddball architectures that use it: alpha, m68k, microblaze, nios2 and openrisc. The fixups should be fairly straightforward ("fix the build errors it exposes by adding the appropriate range arguments"), but the reason this wasn't done in the first place is that so few people end up working on those architectures. But it could be done one architecture at a time, hint, hint.

When trying to load modules built for RISC-V which include assembly files the kernel loader errors with "unexpected relocation type 'R_RISCV_ALIGN'" due to R_RISCV_ALIGN relocations being generated by the assembler. The R_RISCV_ALIGN relocations can be removed at the expense of code space by adding -mno-relax to gcc and as. In commit 7a8e7da4 ("RISC-V: Fixes to module loading") -mno-relax is added to the build variable KBUILD_CFLAGS_MODULE. See [1] for more info. The issue is that when kbuild builds a .S file, it invokes gcc with the -mno-relax flag, but this is not being passed through to the assembler. Adding -Wa,-mno-relax to KBUILD_AFLAGS_MODULE ensures that the assembler is invoked correctly. This may have now been fixed in gcc[2] and this addition should not stop newer gcc and as from working.
