.... I believe it is a mistake to model file_time_type with 128 bits. It would be acceptable if this was absolutely necessary to get the job done, but it isn’t. The 16 byte integer is unnecessarily expensive to get the job done. file_time_type does not need to model the full range and precision of timespec (which on 64 bit platforms is a 128 bit type). All file_time_type needs to model is the full range and precision of what the underlying file system libraries are capable of producing. The latest Linux file system is ext4 (https://en.wikipedia.org/wiki/Ext4) and is capable of nanosecond resolution...

Matt attempted to add CLOCK_TAI support to the VDSO clock_gettime() implementation, which extended the clockid switch case and added yet another slightly different copy of the same code. Especially the extended switch case is problematic as the compiler tends to generate a jump table which then requires to use retpolines. If jump tables are disabled it adds yet another conditional to the existing

In the patch series I posted recently [1], I introduce new system calls to deal with modified data structures, but left the question open on how these should be best accessed from libc. The patches introduce a new __kernel_time64_t type and based on that five new data structured: struct __kernel_timespec, struct __kernel_itimerspec, struct __kernel_stat, struct __kernel_rusage, and struct __kernel_timex. This works fine for the case when all libc implementations provide their own definitions to user space, but not for the simplest case (e.g. klibc) where the user-visible structures come directly fr...

Hi! I've been pondering about doveadm-search-query(7) and trying to formulate a search query for some time now and it seems there is no way to search for messages, which have been marked DELETED before a certain time. I want to use this to expunge all DELETED messages which have been in that state for 24h or longer. For example a cronjob runs at midnight to expunge those messages but a user

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.
