Subject: [PATCH 4/5] ext4 : Add missing posix_acl_release() in ext4_xattr_set_acl() in error path.

This patch fixes the following.

a) Incase journal transaction allocation fails due to ENOMEM don't
call ext4_std_error() since it will
remount the fs as readonly and logs the message in kernel log.
b) Call posix_acl_release() incase journal allocation fails in case of
error paths.

The changelog speaks only about ENOMEM but you actually remove the
message completely (so it won't catch EIO or similar errors). I think you
should just condition ext4_std_error() with if (error != ENOMEM).

Hi Jan,

Thanks for your response. Here is the updated patch.

---------------------------------------------------------------------------------------------------------------------
a) Incase journal transaction allocation fails due to ENOMEM don't call
ext4_std_error() since it will remount the fs as readonly and logs the
message in kernel log.

b) Call posix_acl_release() incase journal allocation fails in case
of error paths.

the fs as readonly and logs the message in kernel log.
