mke2fs was creating both user and group quota inodes on enabling the quota feature. This patch adds the extended option 'quotatype' that can be used to exclusively specify the quota type that the user wants to initialize. # Ex: Default behavior without extended option creates both # user and group quota inodes: $ mke2fs -t ext4 -O quota /dev/ram1 # To enable only user quotas: $ mke2fs -t ext4 -O quota -E quotatype=usr /dev/ram1 # To enable only group quotas: $ mke2fs -t ext4 -O quota -E quotatype=grp /dev/ram1 Signed-off-by: Aditya Kali <redacted> --- misc/mke2fs.8.in | 7 +++++++ misc/mke2fs.c | 24 +++++++++++++++++++++--- 2 files changed, 28 insertions(+), 3 deletions(-)
