Wong" <darrick.wong@...cle.com>, Linus Torvalds <torvalds@...ux-foundation.org> Subject: [PATCH v4 04/16] fs: uapi: define verity bit for FS_IOC_GETFLAGS From: Eric Biggers <ebiggers@...gle.com> 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.
