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
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).
