VFS_SETLEASE(9)                           The Linux VFS                           VFS_SETLEASE(9)



NAME
       vfs_setlease - sets a lease on an open file

SYNOPSIS
       int vfs_setlease(struct file * filp, long arg, struct file_lock ** lease, void ** priv);

ARGUMENTS
       filp
           file pointer

       arg
           type of lease to obtain

       lease
           file_lock to use when adding a lease

       priv
           private info for lm_setup when adding a lease (may be NULL if lm_setup doesn't require
           it)

DESCRIPTION
       Call this to establish a lease on the file. The “lease” argument is not used for F_UNLCK
       requests and may be NULL. For commands that set or alter an existing lease, the
       (*lease)->fl_lmops->lm_break operation must be set; if not, this function will return
       -ENOLCK (and generate a scary-looking stack trace).

       The “priv” pointer is passed directly to the lm_setup function as-is. It may be NULL if
       the lm_setup operation doesn't require it.
