From bc5de0cdb593cf9f8b8df9a8de6f81a0822c7ed5 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 18 Nov 2003 08:15:53 -0800 Subject: [PATCH] [PATCH] ext3_new_inode fixlet From: Alex Tomas If the ext3 inode allocator tries to claim an inode and fails because another CPU got in there first it will then advance onto the next blockgroup and try again. Change it to advance onto the next inode within the same blockgroup instead. --- fs/ext3/ialloc.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/fs/ext3/ialloc.c b/fs/ext3/ialloc.c index 7f0c2bfb81f7b..13f61fc9e85a8 100644 --- a/fs/ext3/ialloc.c +++ b/fs/ext3/ialloc.c @@ -469,8 +469,11 @@ struct inode *ext3_new_inode(handle_t *handle, struct inode * dir, int mode) if (!bitmap_bh) goto fail; - ino = ext3_find_first_zero_bit((unsigned long *) - bitmap_bh->b_data, EXT3_INODES_PER_GROUP(sb)); + ino = 0; + +repeat_in_this_group: + ino = ext3_find_next_zero_bit((unsigned long *) + bitmap_bh->b_data, EXT3_INODES_PER_GROUP(sb), ino); if (ino < EXT3_INODES_PER_GROUP(sb)) { int credits = 0; @@ -493,6 +496,9 @@ struct inode *ext3_new_inode(handle_t *handle, struct inode * dir, int mode) } /* we lost it */ journal_release_buffer(handle, bitmap_bh, credits); + + if (++ino < EXT3_INODES_PER_GROUP(sb)) + goto repeat_in_this_group; } /* -- 2.53.0
