Subject: LUDOC-460 quota: statfs functionality for project quota
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=ea5bec7737925e4371e6f31e6c85e64993e81453;p=doc%2Fmanual.git

LUDOC-460 quota: statfs functionality for project quota

Document the project quota functionality for "df"
and "lfs df" when being run on a directory with project
quota assigned. This will return the amount of space
available to that project rather the total filesystem
space, if the project quota limit is smaller.
