Subject: xfs: use correct state defines in xfs_bmap_del_extent_{cow,delay}
X-Git-Tag: v4.15-rc1~136^2~122
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=0173c689ff4c0855e24ceb898274af1339b5db48;p=linux-block.git

xfs: use correct state defines in xfs_bmap_del_extent_{cow,delay}

Use the _FILLING values to match the usage in the xfs_bmap_add_extent_*
helpers.  No change in behavior, just better naming in the code and
tracepoint output.
