From 9bde9ac78f31214a8c4b18bccc54abd9a809cdc9 Mon Sep 17 00:00:00 2001 From: HuangShujun <549702281@qq.com> Date: Thu, 5 Dec 2019 10:07:10 +0200 Subject: To fix readdir-ahead memory leak Glusterfs client process has memory leak if create serveral files under one folder, and delete the folder. According to statedump, the ref counts of readdir-ahead is bigger than zero in the inode table. Readdir-ahead get parent inode by inode_parent in rda_mark_inode_dirty when each rda_writev_cbk,the inode ref count of parent folder will be increased in inode_parent, but readdir-ahead do not unref it later. The correction is unref the parent inode at the end of rda_mark_inode_dirty Backport of: > Change-Id: Iee68ab1089cbc2fbc4185b93720fb1f66ee89524 > Fixes: bz#1779055 > Signed-off-by: HuangShujun <549702281@qq.com> Change-Id: Iee68ab1089cbc2fbc4185b93720fb1f66ee89524 (cherry picked from commit 99044a5cedcff9a9eec40a07ecb32bd66271cd02) Signed-off-by: Krutika Dhananjay Fixes: bz#1789337 --- xlators/performance/readdir-ahead/src/readdir-ahead.c | 1 + 1 file changed, 1 insertion(+) (limited to 'xlators/performance/readdir-ahead/src/readdir-ahead.c') diff --git a/xlators/performance/readdir-ahead/src/readdir-ahead.c b/xlators/performance/readdir-ahead/src/readdir-ahead.c index 7fd4f8d0618..933941d8a92 100644 --- a/xlators/performance/readdir-ahead/src/readdir-ahead.c +++ b/xlators/performance/readdir-ahead/src/readdir-ahead.c @@ -254,6 +254,7 @@ rda_mark_inode_dirty(xlator_t *this, inode_t *inode) } } UNLOCK(&parent->lock); + inode_unref(parent); } return; -- cgit
