Hi Hugh,
thanks for the fast reply..
Looks like the XFS file system can support files until 16 Tera
when CONFIG_LBDAF is enabled.
On XFS, 32 bit arch, s_maxbytes is actually set (CONFIG_LBDAF=y) as
17592186044415.
But if s_maxbytes doesn't have to be greater than MAX_LFS_FILESIZE,
i agree the

Let's Cc linux-fsdevel, who will be more knowledgable.

Hi all,
running xfstests, generic 308 on whatever 32bit arch is possible
to observe cpu to hang near 100% on unlink.
The test removes a sparse file of length 16tera where only the last
4096 bytes block is mapped.
At line 265 of truncate.c there is a
if (index >= end)
break;
But if index is, a
10 matches
