From 64044abf05d0842a7fed30e102fa411a744c7d9f Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 9 Feb 2013 15:06:24 -0500 Subject: ext4: fix the number of credits needed for ext4_unlink() and ext4_rmdir() The ext4_unlink() and ext4_rmdir() don't actually release the blocks associated with the file/directory. This gets done in a separate jbd2 handle called via ext4_evict_inode(). Thus, we don't need to reserve lots of journal credits for the truncate. Note that using too many journal credits is non-optimal because it can leading to the journal transmit getting closed too early, before it is strictly necessary.
