2006-05-21	[PATCH] NFS server subtree_check returns dubious value	Peter Staubach	1	-1/+1
	Address a problem found when a Linux NFS server uses the "subtree_check" export option. The "subtree_check" NFS export option was designed to prohibit a client from using a file handle for which it should not have permission. The algorithm used is to ensure that the entire path to the file being referenced is accessible to the user attempting to use the file handle. If some part of the path is not accessible, then the operation is aborted and the appropriate version of ESTALE is returned to the NFS client. The error, ESTALE, is unfortunate in that it causes NFS clients to make certain assumptions about the continued existence of the file. They assume that the file no longer exists and refuse to attempt to access it again. In this case, the file really does exist, but access was denied by the server for a particular user. A better error to return would be an EACCES sort of error. This would inform the client that the particular operation that it was attempting was not allowed, without the nasty side effects of the ESTALE error.

2006-01-18	[PATCH] exportfs: add find_acceptable_alias helper	Christoph Hellwig	1	-43/+36
	find_exported_dentry contains two duplicate loops to find an alias that the acceptable callback likes. Split this out to a new helper and switch from list_for_each to list_for_each_entry to make it more readable.

2006-01-09	[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem	Jes Sorensen	1	-6/+6
	This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	2	-0/+546
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
