splice_read: called by the VFS to splice data from file to a pipe. This
method is used by the splice(2) system call
- setlease: called by the VFS to set or release a file lock lease.
- setlease has the file_lock_lock held and must not sleep.
+ setlease: called by the VFS to set or release a file lock lease. setlease
+ implementations should call generic_setlease to record or remove
+ the lease in the inode after setting it.
fallocate: called by the VFS to preallocate blocks or punch a hole.
