Hi all,

After merging the ntfs tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/tmp/next/build/fs/ntfs/attrlist.c:183:6: error: variable 'new_al' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]

      |                    = NULL
2 errors generated.

Caused by commit

  57ad655524e85 (ntfs: protect attribute-list buffer replacement with attr_list_persist_lock)

I have used the tree from next-20260730 instead.
