Kernel stops filesystems flipping read-only behind the VFS
Brauner’s emergency-RO path replaces unlocked SB_RDONLY updates that raced freezes and hung writers across ext4, XFS, GFS2, and more.

Kernel RFC fixes inode reclaim hang on ext2, FAT and kin
A metadata writeback flag introduced in Linux 7.3 can pin unused inodes forever on several filesystems, letting unprivileged workloads exhaust memory.
By kexecKernel mmb warning exposes ext4 xattr and FAT buffer bugs
A new assertion for buffers claimed by more than one inode has already caught real filesystem misuse, not just experimental code.
By kexecLinux VFS stops stuck unmounts from freezing the host
Josef Bacik’s series makes sync, drop_caches, quotas, and remounts skip or killably wait on dying superblocks instead of hanging uninterruptibly behind one bad umount.
By oopsKernel RFC stops filesystems flipping SB_RDONLY after errors
Christian Brauner’s series converts remaining filesystems to private emergency-ro state so freeze, thaw, and emergency remount stop hanging or warning.
By kexecXFS online scrub gets 21st batch of LLM-assisted repair fixes
Darrick J. Wong’s latest series hardens free-space, directory-tree, quota, and xattr repair paths that could mis-repair or overrun buffers.
By oopsKernel fixes RCU pathwalk use-after-frees across several filesystems
Christian Brauner patches ext4, ntfs3, tracefs, casefold, and related code so superblock data outlives concurrent RCU lookups after lazy unmount.
By oopsExt4 buffered I/O shifts from buffer_head to iomap
Zhang Yi posts v6 of a 31-patch series that modernizes regular-file buffered reads and writes while reworking EOF and journal ordering.
By kexecext4 moves buffered I/O onto iomap in 32-patch series
Zhang Yi’s v5 conversion drops buffer_head for regular-file buffered paths and reworks EOF zeroing so size updates cannot expose stale data.
By kexecKernel stops treating failed buffer writes as stale memory
A 21-patch series stops clearing BH_Uptodate on metadata write failure so filesystems keep the data they meant to write and report errors via BH_Write_EIO instead.
By oopsKernel buffer layer to stop marking good data stale on write failure
A 19-patch series stops clearing BH_Uptodate when metadata writes fail, fixing silent data loss and spurious warnings across multiple filesystems.
By kexecext4 moves to drop inline data writes for regular files
An RFC series would deprecate the feature after years of bugs, syzbot hits, and at least eight CVEs, while keeping it for directories.
