This could result in incorrect results. -To handle this zfs_holey_common() was updated to asynchronously -writeback any dirty mmap(2) regions prior to reporting holes. - -Additionally, while not strictly required, the dn_struct_rwlock is -now held over the dirty check to prevent the dnode structure from -changing. This ensures that a clean dnode can't be dirtied before -the data/hole is located. The range lock is now also taken to -ensure the call cannot race with zfs_write(). - -Furthermore, the code was refactored to provide a dnode_is_dirty() -helper function which checks the dnode for any dirty records to -determine its dirtiness. - -Reviewed-by: Matthew Ahrens -Reviewed-by: Tony Hutter -Reviewed-by: Rich Ercolani -Signed-off-by: Brian Behlendorf -Issue #11900 -Closes #12724 ---- - configure.ac | 1 + - include/os/freebsd/spl/sys/vnode.h | 18 +++ - include/os/freebsd/zfs/sys/zfs_znode_impl.h | 3 +- - include/os/linux/zfs/sys/zfs_znode_impl.h | 1 + - include/sys/dnode.h | 1 + - man/man4/zfs.4 | 2 +- - module/zfs/dmu.c | 53 ++++--- - module/zfs/dnode.c | 20 +++ - module/zfs/zfs_vnops.c | 9 +- - tests/runfiles/common.run | 2 +- - tests/zfs-tests/cmd/Makefile.am | 1 + - tests/zfs-tests/cmd/mmap_seek/.gitignore | 1 + - tests/zfs-tests/cmd/mmap_seek/Makefile.am | 6 + - tests/zfs-tests/cmd/mmap_seek/mmap_seek.c | 147 ++++++++++++++++++ - tests/zfs-tests/include/commands.cfg | 1 + - tests/zfs-tests/include/tunables.cfg | 1 + - .../tests/functional/mmap/Makefile.am | 3 +- - .../functional/mmap/mmap_seek_001_pos.ksh | 67 ++++++++ - 18 files changed, 305 insertions(+), 32 deletions(-) - create mode 100644 tests/zfs-tests/cmd/mmap_seek/.gitignore - create mode 100644 tests/zfs-tests/cmd/mmap_seek/Makefile.am - create mode 100644 tests/zfs-tests/cmd/mmap_seek/mmap_seek.c - create mode 100755 tests/zfs-tests/tests/functional/mmap/mmap_seek_001_pos.ksh - -diff --git a/configure.ac b/configure.ac -index 6f34b210d2b..ebc7b276a64 100644 ---- a/configure.ac -+++ b/configure.ac -@@ -221,6 +221,7 @@ AC_CONFIG_FILES([ - tests/zfs-tests/cmd/mktree/Makefile - tests/zfs-tests/cmd/mmap_exec/Makefile - tests/zfs-tests/cmd/mmap_libaio/Makefile -+ tests/zfs-tests/cmd/mmap_seek/Makefile - tests/zfs-tests/cmd/mmapwrite/Makefile - tests/zfs-tests/cmd/nvlist_to_lua/Makefile - tests/zfs-tests/cmd/randfree_file/Makefile -diff --git a/include/os/freebsd/spl/sys/vnode.h b/include/os/freebsd/spl/sys/vnode.h -index 3670712a045..3bc8a18eeb7 100644 ---- a/include/os/freebsd/spl/sys/vnode.h -+++ b/include/os/freebsd/spl/sys/vnode.h -@@ -59,6 +59,8 @@ enum symfollow { NO_FOLLOW = NOFOLLOW }; - #include - #include - #include -+#include -+#include - - typedef struct vop_vector vnodeops_t; - #define VOP_FID VOP_VPTOFH -@@ -83,6 +85,22 @@ vn_is_readonly(vnode_t *vp) - #define vn_has_cached_data(vp) \ - ((vp)->v_object != NULL && \ - (vp)->v_object->resident_page_count > 0) -+ -+static __inline void -+vn_flush_cached_data(vnode_t *vp, boolean_t sync) -+{ -+#if __FreeBSD_version > 1300054 -+ if (vm_object_mightbedirty(vp->v_object)) { -+#else -+ if (vp->v_object->flags & OBJ_MIGHTBEDIRTY) { -+#endif -+ int flags = sync ?
