[Devel] [PATCH vz7 01/46] fuse: initialize fc->release before calling it

[Maxim Patlasov]

Backport from ml:

commit 0ad0b3255a08020eaf50e34ef0d6df5bdf5e09ed

    fuse: initialize fc->release before calling it

    fc->release is called from fuse_conn_put() which was used in the error
    cleanup before fc->release was initialized.

    [Jeremiah Mahler <jmmahler at gmail.com>: assign fc->release after calling
    fuse_conn_init(fc) instead of before.]
