From 40bb0058c871c6ddcd4aff9fe2f5224e59aba47b Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 19 Mar 2014 10:43:59 +0900 Subject: [PATCH] f2fs: avoid to drop nat entries due to the negative nr_shrink The try_to_free_nats should not receive the negative nr_shrink. Otherwise, it can drop all the nat entries by the while loop.
