From: Adrian Bunk Date: Fri, 25 Jul 2008 08:46:34 +0000 (-0700) Subject: coda: remove CODA_FS_OLD_API X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=de0ca06a99c33df8333955642843331ab6b6e7ff;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git coda: remove CODA_FS_OLD_API While fixing CONFIG_ leakages to the userspace kernel headers I ran into CODA_FS_OLD_API. After five years, are there still people using the old API left? Especially considering that you have to choose at compile time which API to support in the kernel (and distributions tend to offer the new API for some time). Jan: "The old API can definitely go. Around the time the new interface went in there were some non-Coda userspace file system implementations that took a while longer to convert to the new API, but by now they all switched to the new interface or in some cases to a FUSE-based solution."
