Subject: quota: Rename quota_update_limits() to quota_read_all_dquots()
X-Git-Tag: v1.46.5~27
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5c87a5c54cc7a78b17dfe4a392cb551d283c353b;p=thirdparty%2Fe2fsprogs.git

quota: Rename quota_update_limits() to quota_read_all_dquots()

quota_update_limits() is a misnomer because what it actually does is
that it updates 'usage' counters and leaves 'limit' counters intact.
Rename quota_update_limits() to quota_read_all_dquots() and while
changing prototype also add a flags argument so that callers can control
which quota information is actually updated from the disk.
