At any rate, a 3 mn git bisect tells me the circular dependency is exposed by this change:
f3fd6cd74fedf99b6060f75df00943fda13b65f2 is the first bad commit commit f3fd6cd74fedf99b6060f75df00943fda13b65f2 Author: Chandan Rajendra chandan@linux.vnet.ibm.com Date: Sat Dec 8 12:21:38 2018 +0530
fscrypt: remove filesystem specific build config option In order to have a common code base for fscrypt "post read" processing for all filesystems which support encryption, this commit removes filesystem specific build config option (e.g.CONFIG_EXT4_FS_ENCRYPTION) and replaces it with a build option (i.e. CONFIG_FS_ENCRYPTION) whose value affects all the filesystems making use of fscrypt.
Signed-off-by: Chandan Rajendra <chandan@linux.vnet.ibm.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>FWIW, The patch at https://patchwork.kernel.org/patch/10725883/ fixes this problem by removing "select BLOCK if FS_ENCRYPTION" from fs/ubifs/Kconfig.
OK
Pierre-Louis, can you check if this patch makes the issue go away for you, please?
Wondering if Chandan provided the right pointer, I wasn't able to apply this patch, but commenting out "select BLOCK if FS_ENCRYPTION" in fs/ubifs/Kconfig makes the circular dependency go away. All good for me.
V4 version of the patchset (which is part of linux-next) had introduced the "select BLOCK if FS_ENCRYPTION". The V5 patchset omits that line. Hence the patch did not apply cleanly. However just commenting out that line was the right thing to do.
