Pull vfs casefolding updates from Christian Brauner: "This exposes the case folding behavior of local filesystems so that file servers - nfsd, ksmbd, and user space file servers - can report the actual behavior to clients instead of guessing. Filesystems report case-insensitive and case-nonpreserving behavior via new file_kattr flags in their fileattr_get implementations. fat, exfat, ntfs3, hfs, hfsplus, xfs, cifs, nfs, vboxsf, and isofs are wired up. Local filesystems that are not explicitly handled default to the usual POSIX behavior of case-sensitive and case-preserving. nfsd uses this to report case folding via NFSv3 PATHCONF and to implement the NFSv4 FATTR4_CASE_INSENSITIVE and FATTR4_CASE_PRESERVING attributes - both have been part of the NFS protocols for decades to support clients on non-POSIX systems - and ksmbd reports it via FS_ATTRIBUTE_INFORMATION. Exposing the information through the fileattr uapi covers user space file servers. The immediate motivation is interoperability: Windows NFS clients hard-require servers to report case-insensitivity for Win32 applications to work correctly, and a client that knows the server is case-insensitive can avoid issuing multiple LOOKUP/READDIR requests searching for case variants. The Linux NFS client already grew support for case-insensitive shares years ago in support of the Hammerspace NFS server - negative dentry caching must be disabled (a lookup for "FILE.TXT" failing must not cache a negative entry when "file.txt" exists) and directory change invalidation must drop cached case-folded name variants. Such servers often operate in multi-protocol environments where a single file service instance caters to both NFS and SMB clients, and nfsd needs to report case folding properly to participate as a first-class citizen there. A follow-up series brings fixes for the initial work: the nfsd case-info probe now uses kernel credentials, maps -ESTALE to NFS3ERR_STALE, and has its cost capped across READDIR entries; the nfs client avoids transiently zeroed case capability bits during the probe and skips the pathconf probe when neither field is consumed; the FS_CASEFOLD_FL semantics are clarified in the UAPI header; and the tools UAPI headers are synced" * tag 'vfs-7.2-rc1.casefold' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (22 commits) nfsd: Cap case-folding probe cost across READDIR entries nfsd: Map -ESTALE from case probe to NFS3ERR_STALE nfsd: Use kernel credentials for case-info probe fs: Clarify FS_CASEFOLD_FL semantics in UAPI header nfs: Skip pathconf probe when neither field is consumed nfs: Avoid transient zeroed case capability bits during probe tools headers UAPI: Sync case-sensitivity flags from linux/fs.h ksmbd: Report filesystem case sensitivity via FS_ATTRIBUTE_INFORMATION nfsd: Implement NFSv4 FATTR4_CASE_INSENSITIVE and FATTR4_CASE_PRESERVING nfsd: Report export case-folding via NFSv3 PATHCONF isofs: Implement fileattr_get for case sensitivity vboxsf: Implement fileattr_get for case sensitivity nfs: Implement fileattr_get for case sensitivity cifs: Implement fileattr_get for case sensitivity xfs: Report case sensitivity in fileattr_get hfsplus: Report case sensitivity in fileattr_get hfs: Implement fileattr_get for case sensitivity ntfs3: Implement fileattr_get for case sensitivity exfat: Implement fileattr_get for case sensitivity fat: Implement fileattr_get for case sensitivity ...
The previous approach maps an architecture string to a function pointer to a function that takes an int errno value and returns a string. The new approach takes an e_machine and an errno value and returns a string. As the only call site is in builtin-trace.c, the e_machine is already present and potentially more specific than the perf_env arch string that is a single global value. Since the errno-to-name mapping is now generated statically and no longer depends on libtraceevent, we can remove the HAVE_LIBTRACEEVENT guards entirely, making perf_env__arch_strerrno unconditionally available. The major complication in this approach is having the shell script that generates the C code map a linux directory name to the matching ELF machine constants. To ensure compatibility with older hosts that have older glibc versions, output fallback definitions for newer ELF machine constants (EM_AARCH64, EM_CSKY, EM_LOONGARCH) if they are not defined in the system <elf.h>.

perf_event_attr__fprintf() accessed all struct fields unconditionally, but attrs from older perf.data files or BPF-captured syscall payloads may have a smaller size than the current struct. Fields beyond the recorded size contain uninitialized or zero-filled data. Add size-guarded macros (PRINT_ATTRn, PRINT_ATTRn_bf) that compare each field's offset against attr->size before accessing it. Guard the bitfield block (disabled, inherit, ... defer_output) with attr_size >= 48. These bitfields share a single __u64 at offset 40, which is within PERF_ATTR_SIZE_VER0 for validated perf.data attrs, but BPF-captured attrs from perf trace can have a smaller size when the tracee passes a minimal struct to sys_perf_event_open. Also fix the BPF trace path: when perf trace intercepts sys_perf_event_open via BPF, the program copies PERF_ATTR_SIZE_VER0 bytes when the tracee passes size=0, but leaves the size field as 0. Set attr->size to PERF_ATTR_SIZE_VER0 in the augmented syscall handler so the bounds checks match the actual copied size.

The only user of msg->msg_iocb was AF_ALG, but that's deprecated. It can be removed entirely at the cost of only supporting synchronous operations. This doesn't break userspace, which will silently block (for a bounded amount of time) in io_submit instead of operating asynchronously. This also makes struct msghdr smaller, helping every other caller of sendmsg().
