[Crash-utility] [PATCH v2 0/4] 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 first 3 patches are used to add large folio support for CRASH. The last patch is newly version of an old patch: it add "files -n" command. v1-->v2: 1.) Rebase the kernel to later 7.0-rc1(merge window) 2.) Fixed a bug in the patch 3, the latest kernel supports folios whose page order is bigger then 5: "xarray: add large folio support" Huang Shijie (4): xarray: add a new parameter for do_xarray add folio_order function xarray: add large folio support add "files -n" command for an inode bpf.c | 8 +++--- defs.h | 10 ++++++- dev.c | 4 +-- diskdump.c | 10 +++++-- filesys.c | 77 ++++++++++++++++++++++++++++++++++++++++++++++-------- help.c | 24 ++++++++++++++++- ipcs.c | 4 +-- kernel.c | 4 +-- memory.c | 26 ++++++++++++++++-- symbols.c | 2 ++ task.c | 4 +-- tools.c | 16 +++++++++--- 12 files changed, 157 insertions(+), 32 deletions(-) -- 2.43.0
