Kernel 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.
