From: Eric Sandeen Date: Thu, 6 Aug 2009 22:07:37 +0000 (-0700) Subject: compat_ioctl: hook up compat handler for FIEMAP ioctl X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=69130c7cf96ea853dc5be599dd6a4b98907d39cc;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git compat_ioctl: hook up compat handler for FIEMAP ioctl The FIEMAP_IOC_FIEMAP mapping ioctl was missing a 32-bit compat handler, which means that 32-bit suerspace on 64-bit kernels cannot use this ioctl command. The structure is nicely aligned, padded, and sized, so it is just this simple. Tested w/ 32-bit ioctl tester (from Josef) on a 64-bit kernel on ext4.
