Vitaliy Filippov 84920d11dd Add vectored read to readbenchfs 
You can now run `./readbenchfs --mount_point dir --vectored` and then
`dd if=dir/test of=/dev/null iflag=direct bs=1M status=progress` to test
vectored read speed.

Results from my laptop (Linux 5.10):

1 core (GOMAXPROCS=1):
- Before vectored read patch: 2.1 GB/s
- Non-vectored read after vectored read patch: 2.1 GB/s
- Vectored read: 2.8 GB/s

All cores:
- Before vectored read patch: 3.0 GB/s
- Non-vectored read after vectored read patch: 3.3 GB/s
- Vectored read: 5.9 GB/s

README.md

ci GoDoc

This package allows for writing and mounting user-space file systems from Go. Install it as follows:

go get -u github.com/jacobsa/fuse

Afterward, see the documentation for the following three packages:

  • Package fuse provides support for mounting a new file system and reading requests from the kernel.

  • Package fuseops enumerates the supported requests from the kernel, and provides documentation on their semantics.

  • Package fuseutil, in particular the FileSystem interface, provides a convenient way to create a file system type and export it to the kernel via fuse.Mount.

Make sure to also see the sub-packages of the samples package for examples and tests.

This package owes its inspiration and most of its kernel-related code to bazil.org/fuse.
