Thanks, The following changes since commit 8f0b4cce4481fb22653697cced8d0d04027cb1e8: Linux 6.19-rc1 (2025-12-14 16:05:07 +1200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs.git tags/f2fs-for-7.0-rc1 for you to fetch changes up to 52190933c37a96164b271f3f30c16099d9eb8c09: f2fs: sysfs: introduce critical_task_priority (2026-02-10 20:53:21 +0000) ---------------------------------------------------------------- f2fs-for-7.0-rc1 In this development cycle, we focused on several key performance optimizations: 1) introducing large folio support to enhance read speeds for immutable files, 2) reducing checkpoint=enable latency by flushing only committed dirty pages, and 3) implementing tracepoints to diagnose and resolve lock priority inversion. Additionally, we introduced the packed_ssa feature to optimize the SSA footprint when utilizing large block sizes. Enhancement: - support large folio for immutable non-compressed case - support non-4KB block size without packed_ssa feature - optimize f2fs_enable_checkpoint() to avoid long delay - optimize f2fs_overwrite_io() for f2fs_iomap_begin - optimize NAT block loading during checkpoint write - add write latency stats for NAT and SIT blocks in f2fs_write_checkpoint - pin files do not require sbi->writepages lock for ordering - avoid f2fs_map_blocks() for consecutive holes in readpages - flush plug periodically during GC to maximize readahead effect - add tracepoints to catch lock overheads - add several sysfs entries to tune internal lock priorities Bug fix: - fix lock priority inversion issue - fix incomplete block usage in compact SSA summaries - fix to show simulate_lock_timeout correctly - fix to avoid mapping wrong physical block for swapfile - fix IS_CHECKPOINTED flag inconsistency issue caused by concurrent atomic commit and checkpoint writes -
