* [KERNEL] Fix build on CentOS 9.5-but-newerSimon Rettberg2024-04-102-4/+16
| | | | | | | | | | So far, breaking changes were accompanied with a bump of the minor version, but not this time. Bewetween -432 and-435, the signature of disk_force_media_change() changed (haha), but the version number stayed the same. Pick the completely arbitrary macro QUEUE_FLAG_SYNCHRONOUS which only exists in -435 to tell the versions apart.

| | | | | It's a function meant for safety, so it refuses to work with pointers that don't start at a page boundary.

| | | | | | Some changes in the block layer were backported from 5.17 to 5.15.132, so our version check regarding the GENHD_FL_NO_PART symbol failed.

| | | | | | We don't have anything in place to actually generate a correct config.h, so to avoid breaking either newer or older distros, don't use the offending syscall at all.

* qcow2: Add lock for lookup cache and decompressionSimon Rettberg2022-03-042-3/+12
| | | | | | | | Race conditions can occur if reads are submitted from different cgroups, as each cgroup has its own workqueue. Linearize the according parts of the code using a mutex, as this will in the worst case lead to performance on par with pre-5.15 versions of xloop, which used one workqueue for all cgroups.
* Add more sanity checks to kernel_read calls and compressed buffer accessSimon Rettberg2022-03-042-25/+105
| | | | | | | Also, while we're at it, add error messages for all (most) failure modes of the cluster reading and decompression code, so we don't just end up with IO errors at the block layer without any clue as to where they were introduced.
* Don't add byte offset to kmapped pointerSimon Rettberg2022-03-041-11/+11
| | | | | | | | While the kunmap functions always round down to the current page, and currently, we never map a region larger than a page, it should be safer to do the pointer arithmetic after we acquired the mapped pointer, to avoid the risk of ever passing an invalid pointer to kunmap.
