From 9902af79c01a8e39bb99b922fa3eef6d4ea23d69 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 15 Apr 2016 15:08:36 -0400 Subject: parallel lookups: actual switch to rwsem ta-da! The main issue is the lack of down_write_killable(), so the places like readdir.c switched to plain inode_lock(); once killable variants of rwsem primitives appear, that'll be dealt with. lockdep side also might need more work Signed-off-by: Al Viro --- fs/readdir.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'fs/readdir.c') diff --git a/fs/readdir.c b/fs/readdir.c index e69ef3b79787..bf583e848a1a 100644 --- a/fs/readdir.c +++ b/fs/readdir.c @@ -32,9 +32,10 @@ int iterate_dir(struct file *file, struct dir_context *ctx) if (res) goto out; - res = mutex_lock_killable(&inode->i_mutex); - if (res) - goto out; + inode_lock(inode); + // res = mutex_lock_killable(&inode->i_mutex); + // if (res) + // goto out; res = -ENOENT; if (!IS_DEADDIR(inode)) { -- cgit v1.2.3
