    [SCSI] osduld: use filp_open() when looking up an osd-device · 021e2230
    Boaz Harrosh authored
    This patch was inspired by Al Viro, for simplifying and fixing the
    retrieval of osd-devices by in-kernel users, eg: file systems.
    In-Kernel users, now, go through the same path user-mode does by
    opening a file on the osd char-device and though holding a reference
    to both the device and the Module.
    A file pointer was added to the osd_dev structure which is now
    allocated for each user. The internal osd_dev is no longer exposed
    outside of the uld. I wanted to do that for a long time so each
    libosd user can have his own defaults on the device.
    The API is left the same, so user code need not change.
    It is no longer needed to open/close a file handle on the osd
    char-device from user-mode, before mounting an exofs on it.
