Subject: [PATCH v9 0/4] VFS: In-kernel copy system call
Date: Tue, 10 Nov 2015 16:53:29 -0500 [thread overview]
Message-ID: <1447192413-15376-1-git-send-email-Anna.Schumaker@Netapp.com> (raw)
Copy system calls came up during Plumbers a while ago, mostly because several
filesystems (including NFS and XFS) are currently working on copy acceleration
implementations. We haven't heard from Zach Brown in a while, so I volunteered
to push his patches upstream so individual filesystems don't need to keep
writing their own ioctls.
Changes in v9:
- Update syscall number for sys_mlock2()
- Fix calls to rw_verify_area()
Thanks,
Anna
Anna Schumaker (1):
vfs: Add vfs_copy_file_range() support for pagecache copies
Zach Brown (3):
vfs: add copy_file_range syscall and vfs helper
x86: add sys_copy_file_range to syscall tables
btrfs: add .copy_file_range file operation
