Author: mav Date: Wed Aug 1 18:28:17 2018 New Revision: 337047 URL: https://svnweb.freebsd.org/changeset/base/337047 Log: 8115 parallel zfs mount Mounting of filesystems in "filesystem/local" is done using `zfs mount -a`, which mounts each filesystems serially. The bottleneck for each mount is the I/O done to load metadata for each filesystem. As such, mounting filesystems using a parallel algorithm should be a big win, and bring down the runtime of "filesystem/local"'s start method. illumos/illumos-gate@591e0e133f9980083db5d64ac33a30bcc3382ff7 Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Pavel Zakharov <pavel.zakharov@delphix.com> Reviewed by: Brad Lewis <brad.lewis@delphix.com> Reviewed by: George Wilson <george.wilson@delphix.com> Reviewed by: Paul Dagnelie <pcd@delphix.com> Reviewed by: Prashanth Sreenivasa <pks@delphix.com> Approved by: Matt Ahrens <mahrens@delphix.com> Author: Sebastien Roy <seb@delphix.com> Modified: vendor-sys/illumos/dist/uts/common/fs/zfs/sys/dsl_pool.h Changes in other areas also in this revision: Added: vendor/illumos/dist/lib/libzfs/common/libzfs_taskq.c (contents, props changed) vendor/illumos/dist/lib/libzfs/common/libzfs_taskq.h (contents, props changed) Modified: vendor/illumos/dist/cmd/zfs/zfs_main.c vendor/illumos/dist/lib/libzfs/common/libzfs.h vendor/illumos/dist/lib/libzfs/common/libzfs_dataset.c vendor/illumos/dist/lib/libzfs/common/libzfs_impl.h vendor/illumos/dist/lib/libzfs/common/libzfs_mount.c Modified: vendor-sys/illumos/dist/uts/common/fs/zfs/sys/dsl_pool.h ============================================================================== --- vendor-sys/illumos/dist/uts/common/fs/zfs/sys/dsl_pool.h Wed Aug 1 17:40:17 2018 (r337046) +++ vendor-sys/illumos/dist/uts/common/fs/zfs/sys/dsl_pool.h Wed Aug 1 18:28:17 2018 (r337047) @@ -89,7 +89,7 @@ typedef struct dsl_pool { struct dsl_dir *dp_leak_dir; struct dsl_dataset *dp_origin_snap; uint64_t dp_root_dir_obj; - struct taskq *dp_vnrele_taskq; + taskq_t *dp_vnrele_taskq; /* No lock needed - sync context only */ blkptr_t dp_meta_rootbp;
