Linux 5.10.3 was released as the first stable update after Christmas.
The changes in Linux 5.10.3 are mainly to fix various small bugs in the entire huge code base, but the problem of severe degradation of Btrfs performance has not been solved yet.
One set of fixes is worth pointing out: There is a problem with the FSCRYPT file system encryption framework used by EXT4, UBIFS, and F2FS. This bug may cause a file to be created while adding the encryption key of the directory, thereby creating duplicate file names.
To fix the problem of duplicate file names in encrypted directories, new code patches have been added to FSCRYPT, as well as UBIFS, EXT4 and F2FS. These patches have been circulating since the end of November, but have not appeared in the stable tree until now.
The specific change log for Linux 5.10.3 can be found on the kernel mailing list .
Linux 5.10 is a "2020" long-term support (LTS) series version and will be maintained until at least 2026.
