Subject: [PATCH 28/31] xfs: clean up the attr flag confusion
Date: Fri, 21 Feb 2020 06:11:51 -0800 [thread overview]
Message-ID: <20200221141154.476496-29-hch@lst.de> (raw)
In-Reply-To: <20200221141154.476496-1-hch@lst.de>
The ATTR_* flags have a long IRIX history, where they a userspace
interface, the on-disk format and an internal interface. We've split
out the on-disk interface to the XFS_ATTR_* values, but despite (or
because?) of that the flag have still been a mess. Switch the
internal interface to pass the on-disk XFS_ATTR_* flags for the
namespace and the Linux XATTR_* flags for the actual flags instead.
The ATTR_* values that are actually used are move to xfs_fs.h with a
new XFS_IOC_* prefix to not conflict with the userspace version that
has the same name and must have the same value.
