[PATCH 2/2] net: apply proc_net_mkdir() harder

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Hallsmark, Per" <Per.Hallsmark@xxxxxxxxxxxxx>

proc_net_mkdir() should be used to create stuff under /proc/net,
so that dentry revalidation kicks in.

See

	commit 1fde6f21d90f8ba5da3cb9c54ca991ed72696c43
	proc: fix /proc/net/* after setns(2)

	[added more chunks --adobriyan]
