## Overview

MinIO implements an S3 extension to perform multiple concurrent fan-out upload operations. A perfect use case scenario for performing fan-out operations of incoming TSB (Time Shift Buffer's). TSBs are a method of facilitating time-shifted playback of television signaling, and media content.

		//   inconsequential to the overall read operation.
		// - xl.meta metadata is still verified for quorum under lock()
		//   however writing the response doesn't need to serialize
		//   concurrent writers
		unlockOnDefer = true
		nsUnlocker = func() { lock.RUnlock(lkctx) }
	}

	fi, metaArr, onlineDisks, err := er.getObjectFileInfo(ctx, bucket, object, opts, true)
	if err != nil {

	}
	return lockedOpenFile(path, flag, perm, lockType)
}

// LockedOpenFile - initializes a new lock and protects
// the file from concurrent access.
func LockedOpenFile(path string, flag int, perm os.FileMode) (*LockedFile, error) {
	var lockType uint32 = lockFileExclusiveLock
	if flag == syscall.O_RDONLY {
