This allows the Merkle tree to be read in larger chunks. - Optimize FS_IOC_ENABLE_VERITY performance in the uncached case by implementing readahead of data pages. - Allocate the hash requests from a mempool in order to eliminate the possibility of allocation failures during I/O. ---------------------------------------------------------------- Eric Biggers (4): fs-verity: implement readahead for FS_IOC_ENABLE_VERITY fs-verity: implement readahead of Merkle tree pages fs-verity: use mempool for hash requests fs-verity: use u64_to_user_ptr() fs/ext4/verity.c | 47 ++++++++++++++++++++- fs/f2fs/data.c | 2 +- fs/f2fs/f2fs.h | 3 ++ fs/f2fs/verity.c | 47 ++++++++++++++++++++- fs/verity/enable.c | 67 +++++++++++++++++++++++------- fs/verity/fsverity_private.h | 17 +++++--- fs/verity/hash_algs.c | 98 +++++++++++++++++++++++++++++++++----------- fs/verity/open.c | 5 ++- fs/verity/verify.c | 47 ++++++++++++++------- include/linux/fsverity.h | 7 +++- 10 files changed, 273 insertions(+), 67 deletions(-)
