[Crash-utility] [PATCH v5 0/5] xarray: add large folio support

The linux kernel supports the large folio for page cache by default. But the current CRASH does not support the large folio. So we may meet the errors when we detected the large folio sometimes, such as in the email: https://www.spinics.net/linux/fedora/redhat-crash-utility/msg11238.html ------------------------------ files: page_to_nid: invalid page: 0 files: page_to_nid: invalid page: 0 files: page_to_nid: invalid page: 0 files: page_to_nid: invalid page: 10 files: page_to_nid: invalid page: 10 files: page_to_nid: invalid page: 10 files: page_to_nid: invalid page: 20 files: page_to_nid: invalid page: 20 files: page_to_nid: invalid page: 20 files: page_to_nid: invalid page: 30 files: page_to_nid: invalid page: 30 files: page_to_nid: invalid page: 30 files: page_to_nid: invalid page: 40 files: page_to_nid: invalid page: 40 files: page_to_nid: invalid page: 40 files: page_to_nid: invalid page: 50 files: page_to_nid: invalid page: 50 files: page_to_nid: invalid page: 50 files: page_to_nid: invalid page: 60 files: page_to_nid: invalid page: 60 ------------------------------ The patch 1 converts the ipcs.c to unix format.
