Subject: [PATCH AUTOSEL 4.19 32/37] Btrfs: fix inode cache block reserve leak on failure to allocate data space
Date: Fri, 25 Oct 2019 09:55:56 -0400 [thread overview]
Message-ID: <20191025135603.25093-32-sashal@kernel.org> (raw)
In-Reply-To: <20191025135603.25093-1-sashal@kernel.org>
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit 29d47d00e0ae61668ee0c5d90bef2893c8abbafa ]
If we failed to allocate the data extent(s) for the inode space cache, we
were bailing out without releasing the previously reserved metadata. This
was triggering the following warnings when unmounting a filesystem:
$ cat -n fs/btrfs/inode.c
(...)
9268 void btrfs_destroy_inode(struct inode *inode)
9269 {
(...)
9276 WARN_ON(BTRFS_I(inode)->block_rsv.reserved);
9277 WARN_ON(BTRFS_I(inode)->block_rsv.size);
(...)
9281 WARN_ON(BTRFS_I(inode)->csum_bytes);
9282 WARN_ON(BTRFS_I(inode)->defrag_bytes);
(...)
Several fstests test cases triggered this often, such as generic/083,
generic/102, generic/172, generic/269 and generic/300 at least, producing
stack traces like the following in dmesg/syslog:
