[Devel] [PATCH RH9 11/28] fs: Export symbols replace_fd() and create_pipe_files()

[Andrey Zhadchenko]

From: Sergey Lysanov <slysanov at virtuozzo.com>

Need to create a pipe for usermodehelper from SCST.
User helper will read SCSI persistent reservations
from pipe and sync it with other nodes in cluster.
Kernel also will read new persistent reservations
from userspace by invoking helper with pipe.

Required for https://pmc.acronis.com/browse/VSTOR-10187
