-Subject: [PATCH 4/9] linux: Use getdents64 on non-LFS readdir
+Date: Tue, 20 Oct 2020 13:37:15 -0300
+Subject: [PATCH 1/3] linux: Use getdents64 on non-LFS readdir
-The non-LFS opendir reserves a translation entry to be used to return
-the entry and the dirent64 struct is translated to the temporary buffer
-on each readdir call.
-
-Entries that overflow d_off/d_ino and the buffer reallocation failure
-(in case of large d_name) are ignored.
+It is similar to what non-LFS getdents do (including overflow check).
Checked on x86_64-linux-gnu and i686-linux-gnu.

-Subject: [PATCH 8/9] linux: Use getdents64 on readdir64 compat implementation
-
-It uses a similar strategy from the non-LFS readdir that also
-uses getdents64 internally and uses a translation buffer to return
-the compat readdir64 entry.
-
-It allows to remove __old_getdents64.
-
-Checked on i686-linux-gnu.
