Currently when acquiring an sb for virtiofs fuse_mount_get() is being called from virtio_fs_set_super() if a new sb is being filled and fuse_mount_put() is called unconditionally after sget_fc() returns. The exact same result can be obtained by checking whether fs_contex->s_fs_info was set to NULL (ref trasferred to sb->s_fs_info) and only calling fuse_mount_put() if the ref wasn't transferred (error or matching sb found). This allows getting rid of virtio_fs_set_super() and fuse_mount_get(). Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
