Subject: [013/197] xfs: Fix error return for fallocate() on XFS
Date: Thu, 22 Apr 2010 12:07:44 -0700	[thread overview]
Message-ID: <20100422190908.571068638@kvm.kroah.org> (raw)
In-Reply-To: <20100422191857.GA13268@kroah.com>

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------


From: Jason Gunthorpe <jgunthorpe@obsidianresearch.com>

commit 44a743f68705c681439f264deb05f8f38e9048d3 upstream

Noticed that through glibc fallocate would return 28 rather than -1
and errno = 28 for ENOSPC. The xfs routines uses XFS_ERROR format
positive return error codes while the syscalls use negative return
codes.  Fixup the two cases in xfs_vn_fallocate syscall to convert to
negative.
