From: Eric Biggers Date: Mon, 22 Jul 2019 16:26:21 +0000 (-0700) Subject: fs: uapi: define verity bit for FS_IOC_GETFLAGS X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fe9918d3b228b3e8c726849d1486933f46b9069e;p=linux.git fs: uapi: define verity bit for FS_IOC_GETFLAGS Add FS_VERITY_FL to the flags for FS_IOC_GETFLAGS, so that applications can easily determine whether a file is a verity file at the same time as they're checking other file flags. This flag will be gettable only; FS_IOC_SETFLAGS won't allow setting it, since an ioctl must be used instead to provide more parameters. This flag matches the on-disk bit that was already allocated for ext4.
