Date: Fri, 29 Mar 2019 20:55:30 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Lukas Czerner <lczerner@...hat.com>, Theodore Ts'o <tytso@....edu>, Sasha Levin <sashal@...nel.org>, linux-ext4@...r.kernel.org Subject: [PATCH AUTOSEL 4.9 04/27] ext4: report real fs size after failed resize From: Lukas Czerner <lczerner@...hat.com> [ Upstream commit 6c7328400e0488f7d49e19e02290ba343b6811b2 ] Currently when the file system resize using ext4_resize_fs() fails it will report into log that "resized filesystem to <requested block count>". However this may not be true in the case of failure. Use the current block count as returned by ext4_blocks_count() to report the block count. Additionally, report a warning that "error occurred during file system resize" Signed-off-by: Lukas Czerner <lczerner@...hat.com> Signed-off-by: Theodore Ts'o <tytso@....edu> Signed-off-by: Sasha Levin <sashal@...nel.org> --- fs/ext4/resize.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/fs/ext4/resize.c b/fs/ext4/resize.c index e16fb545d441..aef2a24dc9f9 100644 --- a/fs/ext4/resize.c +++ b/fs/ext4/resize.c @@ -2047,6 +2047,10 @@ int ext4_resize_fs(struct super_block *sb, ext4_fsblk_t n_blocks_count) free_flex_gd(flex_gd); if (resize_inode != NULL) iput(resize_inode); - ext4_msg(sb, KERN_INFO, "resized filesystem to %llu", n_blocks_count); + if (err) + ext4_warning(sb, "error (%d) occurred during " + "file system resize", err); + ext4_msg(sb, KERN_INFO, "resized filesystem to %llu", + ext4_blocks_count(es)); return err; } -- 2.19.1
