Subject: libxfs: use XFS_IGET_CREATE when creating new files
X-Git-Tag: v6.5.0~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7f5bbe286e02b0c7df72aba386b56af92b812dc3;p=thirdparty%2Fxfsprogs-dev.git

libxfs: use XFS_IGET_CREATE when creating new files

Use this flag to check that newly allocated inodes are, in fact,
unallocated.  This matches the kernel, and prevents userspace programs
from making latent corruptions worse by unintentionally crosslinking
files.
