Jann, I noticed a report about a regression in bugzilla.kernel.org that appears to be caused directly or indirectly by a change of yours: 3cad1bc010416c ("filelock: Remove locks reliably when fcntl/close race is detected") [v6.10-rc7] As many (most?) kernel developers don't keep an eye on the bug tracker, I decided to write this mail. To quote from https://bugzilla.kernel.org/show_bug.cgi?id=219075 : > On my 2023, LG Gram laptop (kernel 6.9.10), the Laptop extra features > stopped working, and like in > https://bugzilla.kernel.org/show_bug.cgi?id=218901, none of the > kernel variables for the are writable. for example, trying to write > 80 to `/sys/devices/platform/lg-laptop/battery_care_limit` or > `/sys/class/power_supply/BAT0/charge_control_end_threshold` results > in 0 when running cat.

See the ticket for more details and additional comments. Note, you have to use bugzilla to reach the reporter, as I sadly[1] can not CCed them in mails like this. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. [1] because bugzilla.kernel.org tells users upon registration their "email address will never be displayed to logged out users" P.S.: let me use this mail to also add the report to the list of tracked regressions to ensure it's doesn't fall through the cracks: #regzbot introduced: 3cad1bc010416c6dd780643476bc59ed742436b9 #regzbot title: vfs/platform-drivers: LG Gram Laptop Extra Features stopped working #regzbot from: Chris #regzbot duplicate: https://bugzilla.kernel.org/show_bug.cgi?id=219075 #regzbot ignore-activity
