Hi Linus, Could you consider these fixes for 6.8-rc3?
One commit fixes an infinite loop issue of sub-page compressed data support found with lengthy stress tests on a 64k-page arm64 VM. Another one optimizes temporary buffer allocation for low-memory scenarios, which can reduce 20.21% on average under a heavy multi-app launch benchmark workload. The remaining one gets rid of unnecessary GFP_NOFS. All commits have been in -next for a while and no potential merge conflict is observed. Thanks, Gao Xiang The following changes since commit 6613476e225e090cc9aad49be7fa504e290dd33d: Linux 6.8-rc1 (2024-01-21 14:11:32 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs.git tags/erofs-for-6.8-rc3-fixes for you to fetch changes up to d9281660ff3ffb4a05302b485cc59a87e709aefc: erofs: relaxed temporary buffers allocation on readahead (2024-01-27 12:28:08 +0800) ---------------------------------------------------------------- Changes since last update: - Fix infinite loops due to filling compressed_bvecs non-atomically; - Remove unnecessary GFP_NOFS; - Relax temporary buffer allocation for low-memory scenarios. ---------------------------------------------------------------- Chunhai Guo (1): erofs: relaxed temporary buffers allocation on readahead Gao Xiang (1): erofs: fix infinite loop due to a race of filling compressed_bvecs Jingbo Xu (1): erofs: get rid of unneeded GFP_NOFS fs/erofs/compress.h | 5 +-- fs/erofs/decompressor.c | 5 ++- fs/erofs/decompressor_deflate.c | 19 +++++--- fs/erofs/decompressor_lzma.c | 17 ++++--- fs/erofs/fscache.c | 2 +- fs/erofs/inode.c | 2 +- fs/erofs/utils.c | 2 +- fs/erofs/zdata.c | 98 +++++++++++++++++++++++------------------ 8 files changed, 87 insertions(+), 63 deletions(-)
