Subject: fs/ntfs3: Keep runs for $MFT::$ATTR_DATA and $MFT::$ATTR_BITMAP
X-Git-Tag: v6.11-rc1~82^2~8
X-Git-Url: https://gentwo.org/gitweb/?a=commitdiff_plain;h=eb95678ee930d67d79fc83f0a700245ae7230455;p=linux%2F.git

fs/ntfs3: Keep runs for $MFT::$ATTR_DATA and $MFT::$ATTR_BITMAP

We skip the run_truncate_head call also for $MFT::$ATTR_BITMAP.
Otherwise wnd_map()/run_lookup_entry will not find the disk position for the bitmap parts.

Fixes: 0e5b044cbf3a ("fs/ntfs3: Refactoring attr_set_size to restore after errors")
