Subject: [PATCH 07/24] tools headers uapi: Sync linux/fs.h with the kernel sources
Date: Tue, 1 Oct 2019 08:11:59 -0300 [thread overview]
Message-ID: <20191001111216.7208-8-acme@kernel.org> (raw)
In-Reply-To: <20191001111216.7208-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To pick the changes from:
78a1b96bcf7a ("fscrypt: add FS_IOC_REMOVE_ENCRYPTION_KEY_ALL_USERS ioctl")
23c688b54016 ("fscrypt: allow unprivileged users to add/remove keys for v2 policies")
5dae460c2292 ("fscrypt: v2 encryption policy support")
5a7e29924dac ("fscrypt: add FS_IOC_GET_ENCRYPTION_KEY_STATUS ioctl")
b1c0ec3599f4 ("fscrypt: add FS_IOC_REMOVE_ENCRYPTION_KEY ioctl")
22d94f493bfb ("fscrypt: add FS_IOC_ADD_ENCRYPTION_KEY ioctl")
3b6df59bc4d2 ("fscrypt: use FSCRYPT_* definitions, not FS_*")
2336d0deb2d4 ("fscrypt: use FSCRYPT_ prefix for uapi constants")
7af0ab0d3aab ("fs, fscrypt: move uapi definitions to new header <linux/fscrypt.h>")
That don't trigger any changes in tooling, as it so far is used only
for:
$ grep -l 'fs\.h' tools/perf/trace/beauty/*.sh | xargs grep regex=
tools/perf/trace/beauty/rename_flags.sh:regex='^[[:space:]]*#[[:space:]]*define[[:space:]]+RENAME_([[:alnum:]_]+)[[:space:]]+\(1[[:space:]]*<<[[:space:]]*([[:xdigit:]]+)[[:space:]]*\)[[:space:]]*.*'
tools/perf/trace/beauty/sync_file_range.sh:regex='^[[:space:]]*#[[:space:]]*define[[:space:]]+SYNC_FILE_RANGE_([[:alnum:]_]+)[[:space:]]+([[:xdigit:]]+)[[:space:]]*.*'
tools/perf/trace/beauty/usbdevfs_ioctl.sh:regex="^#[[:space:]]*define[[:space:]]+USBDEVFS_(\w+)(\(\w+\))?[[:space:]]+_IO[CWR]{0,2}\([[:space:]]*(_IOC_\w+,[[:space:]]*)?'U'[[:space:]]*,[[:space:]]*([[:digit:]]+).*"
tools/perf/trace/beauty/usbdevfs_ioctl.sh:regex="^#[[:space:]]*define[[:space:]]+USBDEVFS_(\w+)[[:space:]]+_IO[WR]{0,2}\([[:space:]]*'U'[[:space:]]*,[[:space:]]*([[:digit:]]+).*"
$
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/fs.h' differs from latest version at 'include/uapi/linux/fs.h'
