From e0b8e8b65d578f5d5538465dff8392cf02e1cc5d Mon Sep 17 00:00:00 2001 From: Tim Shimmin Date: Thu, 30 Oct 2008 18:30:48 +1100 Subject: [XFS] remove restricted chown parameter from xfs linux On Linux all filesystems are supposed to be operating under Posix' restricted chown. Restricted chown means it restricts chown to the owner unless you have CAP_FOWNER. NOTE: that 2 files outside of fs/xfs have been modified too for this change.

This is a Bad Thing. Fix the race by checking whether we are still initialising the inod eonce we have a reference to it, and if so wait for the initialisation to complete before continuing. While there, fix a leaked reference count in the same code when encountering an unlinked inode and we are not doing a lookup for a create operation.

As far as the kernel and most userspace is concerned this works perfectly, but applications still using really old stat and readdir interfaces will get an EOVERFLOW error when hitting an inode number not fitting into 32 bits (that problem of course also exists when using these applications on a 64bit kernel). Note that because inode64 is simply a mount option we can currently mount a filesystem having > 32 bit inode numbers and cause a variety of problems, all this is solved but this patch which enables XFS_BIG_INUMS, even when inode64 is not used.
