[for-linus][PATCH 0/3] tracing: A few fixes for 6.5
From: Steven Rostedt
Date: Wed Jul 05 2023 - 10:46:42 EST
Tracing fixes for 6.5:
- Fix bad git merge of #endif in arm64 code
A merge of the arm64 tree caused #endif to go into the wrong place
- Fix crash on lseek of write access to tracefs/error_log
Opening error_log as write only, and then doing an lseek() causes
a kernel panic, because the lseek() handle expects a "seq_file"
to exist (which is not done on write only opens). Use tracing_lseek()
that tests for this instead of calling the default seq lseek handler.
- Check for negative instead of -E2BIG for error on strscpy() returns
Instead of testing for -E2BIG from strscpy(), to be more robust,
check for less than zero, which will make sure it catches any error
that strscpy() may someday return.
