From 292db1bc6c105d86111e858859456bcb11f90f91 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sun, 21 Jun 2015 21:10:51 -0400 Subject: [PATCH] ext4: don't retry file block mapping on bigalloc fs with non-extent file ext4 isn't willing to map clusters to a non-extent file. Don't signal this with an out of space error, since the FS will retry the allocation (which didn't fail) forever. Instead, return EUCLEAN so that the operation will fail immediately all the way back to userspace. (The fix is either to run e2fsck -E bmap2extent, or to chattr +e the file.)
