Merge tag 'pull-xattr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull xattr updates from Al Viro:
"Sanitize xattr and io_uring interactions with it, add *xattrat()
syscalls, sanitize struct filename handling in there"
* tag 'pull-xattr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
xattr: remove redundant check on variable err
fs/xattr: add *at family syscalls
new helpers: file_removexattr(), filename_removexattr()
new helpers: file_listxattr(), filename_listxattr()
replace do_getxattr() with saner helpers.
replace do_setxattr() with saner helpers.
new helper: import_xattr_name()
fs: rename struct xattr_ctx to kernel_xattr_ctx
xattr: switch to CLASS(fd)
io_[gs]etxattr_prep(): just use getname()
io_uring: IORING_OP_F[GS]ETXATTR is fine with REQ_F_FIXED_FILE
getname_maybe_null() - the third variant of pathname copy-in
teach filename_lookup() to treat NULL filename as ""
