Subject: Re: [PATCH 4/4] XFS: Unicode case-insensitive lookup implementation
Date: Mon, 21 Apr 2008 05:15:20 -0400	[thread overview]
Message-ID: <20080421091520.GA31070@infradead.org> (raw)
In-Reply-To: <20080421083645.799556386@chook.melbourne.sgi.com>

The patch looks quite clean, but there still is the fundamental issue
of rejecting perfectly fine UNIX filenames in xfs_unicode_validate,
as discussed in the last round a Unix filename is any valid
NULL-terminated bytestream with only ".", "..", and "/" special-cased
and this patch breaks this assumptions.

In addition to that I think xfs_unicode.[ch] should be split into
a small xfs-specific part for reading the on-disk case-folding table
and implementing the actual nameops, and the generic code for case
folding and compares and case-folded strings should be moved into lib/
as it's quite generic.
