From: Eric Paris Date: Thu, 26 May 2011 02:49:18 +0000 (-0700) Subject: tmpfs: fix XATTR N overriding POSIX_ACL Y X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4db70f73e56961b9bcdfd0c36c62847a18b7dbb5;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git tmpfs: fix XATTR N overriding POSIX_ACL Y Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL, even if it had been Y in oldconfig; and Linus reports that PulseAudio goes subtly wrong unless it can use ACLs on /dev/shm. Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS), and move the TMPFS_POSIX_ACL entry before the TMPFS_XATTR entry, to avoid asking unnecessary questions then ignoring their answers.
