The patch titled
replacement patch for pipefs and sockfs
has been removed from the -mm tree. Its filename was
have-pipefs-ensure-i_ino-uniqueness-by-calling-iunique-and-hashing-the-inode-update.patch
This patch was dropped because it was folded into
have-pipefs-ensure-i_ino-uniqueness-by-calling-iunique-and-hashing-the-inode.patch
------------------------------------------------------
Subject: replacement patch for pipefs and sockfs
From: Jeff Layton <[EMAIL PROTECTED]>
pipefs declares its drop_inode function to be generic_delete_inode, which
obviates the need to have the fs make certain that i_nlink is properly set at
drop_inode time.
