Yes, I used "compression_extension=*" in my tests. > But also, we don't really need to skip these tests. Instead, how about > using 'chattr +m' to explicitly set the test file to uncompressed? I tried that and "chattr +m" does not work as it tries to simultaneously set 2 mutually exclusive compression flags (FS_COMPR_FL and FS_NOCOMP_FL). However, "chattr -c" on an empty file works, so let me post a v2 attempt shortly. Thanks!
