Pull common SETFLAGS/FSSETXATTR parameter checking from Darrick Wong: "Here's a patch series that sets up common parameter checking functions for the FS_IOC_SETFLAGS and FS_IOC_FSSETXATTR ioctl implementations. The goal here is to reduce the amount of behaviorial variance between the filesystems where those ioctls originated (ext2 and XFS, respectively) and everybody else. - Standardize parameter checking for the SETFLAGS and FSSETXATTR ioctls (which were the file attribute setters for ext4 and xfs and have now been hoisted to the vfs) - Only allow the DAX flag to be set on files and directories" * tag 'vfs-fix-ioctl-checking-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: vfs: only allow FSSETXATTR to set DAX flag on files and dirs vfs: teach vfs_ioc_fssetxattr_check to check extent size hints vfs: teach vfs_ioc_fssetxattr_check to check project id info vfs: create a generic checking function for FS_IOC_FSSETXATTR vfs: create a generic checking and prep function for FS_IOC_SETFLAGS

ext2: Use kmemdup rather than duplicating its implementation

2019-07-03T14:24:25Z

kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memset, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memset.

vfs: create a generic checking and prep function for FS_IOC_SETFLAGS

2019-07-01T15:25:34Z

Create a generic function to check incoming FS_IOC_SETFLAGS flag values and later prepare the inode for updates so that we can standardize the implementations that follow ext4's flag values. Note that the efivarfs implementation no longer fails a no-op SETFLAGS without CAP_LINUX_IMMUTABLE since that's the behavior in ext*. Signed-off-by: Darrick J.
