X-Git-Tag: 2.6.92~79
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=9dacbee7fe35e7dac5637c8ad5c62ece41d3c8ed

LU-5772 osd-zfs: irrelevant comment over __osd_xattr_load

Moved comment over __osd_xattr_load() to __osd_xattr_get(),
where it really belongs, and converted it to Doxygen format.
Added a few other minor cleanups as well.
