Subject: [PATCH 13/20] perf report/tui: Fix a bug when --fields/sort is given
Date: Mon, 19 May 2014 15:25:55 +0900	[thread overview]
Message-ID: <1400480762-22852-14-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1400480762-22852-1-git-send-email-namhyung@kernel.org>

The hists__filter_entries() function is called when down arrow key is
pressed for navigating through the entries in TUI.  It has a check for
filtering out entries that have very small overhead (under min_pcnt).

However it just assumed the entries are sorted by the overhead so when
it saw such a small overheaded entry, it just stopped navigating as an
optimization.  But it's not true anymore due to new --fields and
--sort optoin behavior and this case users cannot go down to a next
entry if ther's an entry with small overhead in-between.
