[patch 63/85] scripts/gdb: replace flags (MS_xyz -> SB_xyz)

by akpm＠linux-foundation.org

From: Jackie Liu <liuyun01(a)kylinos.cn> Subject: scripts/gdb: replace flags (MS_xyz -> SB_xyz) Since 1751e8a6cb93 ("Rename superblock flags (MS_xyz -> SB_xyz)"), scripts/gdb should be updated to replace MS_xyz with SB_xyz. This change didn't directly affect the running operation of scripts/gdb until e262e32d6bde "vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled" removed the definitions used by constants.py. Update constants.py.in to utilise the new internal flags, matching the implementation at fs/proc_namespace.c::show_sb_opts. Note to stable, e262e32d6bde landed in v5.0-rc1 (which was just released), so we'll want this picked back to 5.0 stable once this patch hits mainline (akpm just picked it up). Without this, debugging a kernel a kernel via GDB+QEMU is broken in the 5.0 release.

[PATCH for-4.19] staging: erofs: fix mis-acted TAIL merging behavior

by Gao Xiang

commit a112152f6f3a2a88caa6f414d540bd49e406af60 upstream. EROFS has an optimized path called TAIL merging, which is designed to merge multiple reads and the corresponding decompressions into one if these requests read continuous pages almost at the same time. In general, it behaves as follows: ________________________________________________________________ ... | TAIL . HEAD | PAGE | PAGE | TAIL . HEAD | ... _____|_combined page A_|________|________|_combined page B_|____ 1 ] -> [ 2 ] -> [ 3 If the above three reads are requested in the order 1-2-3, it will generate a large work chain rather than 3 individual work chains to reduce scheduling overhead and boost up sequential read. However, if Read 2 is processed slightly earlier than Read 1, currently it still generates 2 individual work chains (chain 1, 2) but it does in-place decompression for combined page A, moreover, if chain 2 decompresses ahead of chain 1, it will be a race and lead to corrupted decompressed page. This patch fixes it.
