[Devel] [PATCH rhel7] procfs: always expose /proc//map_files/ and make it readable

[Devel] [PATCH 5/6] e4defrag2: prevent agressive donor lookup

It was bad idea to try all dirs from all groups for donor especially for big filesystems. Let's scan only local ones. Signed-off-by: Dmitry Monakhov --- misc/e4defrag2.c |5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/misc/e4defrag2.c b/misc/e4defrag2.c index 771ee5
