+To use this patch, run these commands for a successful build:
+ patch -p1 <patches/acls.diff
+ patch -p1 <patches/adaptec_acl_mods.diff
./prepare-source
./configure --enable-acl-support
make
I (Wayne) tweaked the patch for style and to avoid using SMB_* constants
with literal values were needed.
+I've also updated it to apply to the updated version of the acls.diff,
+though I don't know if there might be some bits lost in the current
+algorithm when using the file's mode bits to reconstruct a stripped ACL
+entry.
